Ospho is an acid and you shouldn't be inhaling it. I normally do that kind of stuff outside but I don't normally wear a respirator. As long as you can't really smell it you should be good. Of course I could be wrong...

"Use adequate ventilation in confined areas"

I took my radiator in to have it boiled today. The guy said he thought it had been re-cored, or repaired.  It has three rows of fins, my understanding is the original had two rows?  Here's a few pictures 

 

 

When you were talking about the radiator earlier, I almost chimed in to say you could keep the stock look and just go to a three row radiator core if cooling is an issue. Evidently that has already happened. You shouldn't have cooling issues, at least due to the available cooling area...

Cars fitted with AC usually had 3 row radiators . The stock radiators flow really well.

My car had the dealer-installed A/C when I bought it new, the original 2-row was in place.  It did not hold up well and after several repairs I had it re-cored with a three row, still in the car today.

Any idea if  this is stock? Is the top and bottom stock? If it’s bad I might replace the core with aluminum and keep the rest original? Thoughts? 

 

In in the process of replacing my heater hoses. The grommets on the firewall are bad, any idea where I can get replacements? 

 

This photo shows the fit of my tank with the original long strap. It’s pretty tight. My tank may have expanded during the boiling, any ideas how to make this fit? 

Your tanks and frame are stock.  The lower tank shows the radiator came out of an automatic transmission car.

Your grommets are here: https://www.240zrubberparts.com/apps/webstore/products/show/4842851

And... I have a set of Nissan NOS grommets for $30 if you are interested.

I also don't know what they are for. Are they the grommets I need, plus some, or just the ones I need?  Sorry, I'm new to this.  

Did you get the pads right, maybe they are too thick?
