Z car rust


Tourniqet

Recommended Posts

I just found out that my 73 z has about 5 inches of rust on the bottom part of the back of the frame rail attaching it to the rest of the frame. I thought I checked the whole car before buying but oh well. I will try to post a picture of it. I dont know what to do, I have never had any rust repair experience and was wondering what the first steps should be...

Thanks

It's going to all depend on how bad it is. I could be surface rust that just sands off or a 5 inch hole or something in between. You'll need to show us the pictures. That part of the car is very important structurally. If it's bad it has to be repaired properly. You can get new frame rails from here:

The rust is about six inches long along the frame rail directly under the passenger seat...

Man, I have been here before....

You can get away with just patching this area, but for the price it's better to just get a set of floor pan panels. These can range from $150-$300 depending on the "correctness" of the panels.

The repair itself is pretty easy is you are somewhat competent with a welder. Otherwise, find someone that will do the work *and* do a good job.

Since you're in Dallas, contact the Z Club of Texas (a link is posted in this site in the links section). There are quite a few people up there that will be willing to help.

If the floor pans are in good shape other than the one spot that is rusted out, you might also consider patching the spot on the floor, and replacing only the under floor rail which you can get from Zedd Findings.

Seriously though, the best thing to do is to get under there and find out what is or is not hiding under the undercoating before you go any further... Looks to be quite a good coating of undercoat on the car, so you may or may not have more rust than you think you have.

Actually the front floor pans are good shape rust wise but they have about a 4 inch tare in them... no rust around it just looks like someone jamed a screwdriver through it and tore it down 4 or 5 inches. This car has been in rural texas all its life, so it most definantly could be some teenagers offroading in it. You know how those country folk are :classic:
