yea 4 something, but you can find shops that will still work with R-12 and it works pretty well. If you get new stuff under the hood (mainly the condenser) then R-134a would prob work fine, may work with the OE condenser, just not sure as I have not tried that. There are a lot of options for refrigerents including "dust off". You just have to know what kind of oils etc... the advantage of R-12 is you don't have to worry as much about oil compatibility.

Of course if you are replacing all the under the hood stuff  only have to worry about purging the evap with some cleaning solvent.

Just watched a YouTube which referenced "Enviro?" as a safe replacement for R12. I do all my own labor except welding, fine bodywork and paint. Prior projects Have helped me find my limits - and I'm old enough not to delude myself ;).

Below will be the cars new home and workshop - getting organized.

that's a propane and 134a mix I think. You should have no problems with the simple system based on your shop pic, anybody with a lift can do it. Just check that condenser for leaks that's the biggest problem. I was luck to find a NOS OE unit. the used stuff sold on ebay is iffy.

I agree with siteunseen on SEM for panel colors. Paint panel works really good on panels that don't get rubbed very much. I would work on cleaning the door cards and armrest with some good cleaners.

As for AC I would consider upgrading to a rotary AC compressor ...

Beautiful, and looks like an unmolested example. I wish mine had been that un-messed with when I got it.

However, with no bubble bursting intended... That's not original paint. It's been sprayed.

Not busting any dreams. If it was sprayed it was a long time ago. Its kinda like my dad (74). Love him but over the years I've picked up some work or a project he has done and scratched my head - if it worked was good enough. Not sure what is under if has been sprayed. Will be on my lift next weekend and go through - regardless looks to be straight. Rust and bondo are my biggest fears - but as I said I've known the car and can vouch was never in an accident and never had major work done. It is possible PO sprayed it when he first got it - I know he had underbody treated with some tar/oil coat. Will let you all know - curious what paint meter will say. Will get treatment with a magnet and microfiber too.

Good. Was hoping I wasn't crushing hopes and dreams... That's always a risk.

So if I'm not mistaken (which is certainly not a given!!), I don't think a paint gauge will be necessary. It appears there is overspray:

On the rubber bumpers on the top edge of the fenders that align the sides of the hood
On the windshield washer bottle
On the top of the pass door jamb latch
Along the bottom of the pass door sill plate
On the rubber door seals at the upper front corners of the doors (in front of the side view mirrors)

Great eye - and if body proves sound / minimal effort then I won't feel so bad about some of the changes I was considering. You are right on the rubber and sills - once pointed out can see. Unfortunately the guy that could answer isn't here. Like a box of chocolates :)

Look's like you're got a great base to start off from. That lift is sure to come in handy.  Add another vote for SEM. I did mine in the ginger color.  Had it custom mixed  and put into rattle cans at the paint supplier.  The interior panels (not the vinyl) needed a water based paint and had to be cleaned/degreased first,  then sprayed with an SEM product called Sand Free. Then apply the paint immediately after.  It has held up well.

Agreed! I think it looks great and I wish mine was that original. My PO applied paint is just one of a multitude of things that have been messed with on mine!

If I were closer, I'd be happy to come over and swap interiors with you. I've got the black and have been digging the white for quite some time.

Flash back for me.  I spent my life with my dad doing this!  He was a mechanical Engineer and always thought he could make things better.  Sometimes yes sometimes no.

I think I was 14 or so and my dad decided to re-work my RC car transmission.  A main, final race in third and only a few corners to catch the leader and my car just stopped.  I was not happy.  That race cost me the State Championship in 84!

My Dad (78) still does this and I have to figure out what he did and try and make it right without spending a dime, not working he says there's no money to pay out. That's a crock of sh*t.

Thank goodness for the internet, now I'm a lawnmower mechanic, an electrician and a plumber to him. LOL

I'll be clear - my dad has taught me so much and has helped me the most when I need it. I learned to MacGyver from him. He comes from an era of Model T tubs hot rodded out - what we would call rat rods. They would figure stuff out before the internet and don't care about pretty.

But that also means doing things like taking bags of dry chlorine (Shock treatment for pool) and cramming into a bucket he then puts next to my S2000. He put them in the bucket because one was leaking granules. Rusted my chrome (shocks, exhaust tip, emblems) within a week before I caught. He's stubborn too - nothing can't be fixed without a bigger hammer. Lots of broken bolts to prove this - I've gotten good with a drill and tap....

Still and always great fun to work with him and I'm sure my son will bitch about me one day.

Totally understand.  My dad passed 3 years ago at 72 and Miss him dearly.  Be sure to ask him any questions now before you forget.  You never know when we'll be called home.

SWMBO is in Orlando this week, but no... I wasn't invited this time.

We could have had a convoy from Orlando to Boca!   B)

Be great to have help this weekend - I'm grinding the concrete floor in the garage and putting down the RockSolid Copper Metallic flooring :). Very excited - haven't seen the car in a few years and now it is mine! The ZX wheels will be coming off in next month, along with all the other projects. Curious how quickly I'll pick up working on this - the first time you work on a new car or do something it takes 4x as long as the second time. That rule seems to hold on every vehicle and boat I've worked on.

they are stupid easy to work on as long as the bolts don't break. So far the hardest job for me was removing the heat shield. I hear that working on the rear suspension (control arm bushings and wheel bearings) can be a pain. all comes down to if things are seriously stuck.

1st things I did was fluids (use yellow metal safe oil in the trans), belts and hoses,T stat, water pump (well after it leaked),alt (after it shorted out), FI rubber hoses with correct clamps.

the list goes on but you get the picture, mainly simple stuff that was done wrong (like wrong hoses and clamps on FI) normal maint, and electrical connections including new rubber boots to keep out moisture.

Sensors on the T stat housing are often bad. Hopefully no one has monkeyed around with the AFM, it seems to be the go to thing anytime the FI is not working right.
