Hi, I am currently restoring a 1979 firebird and turns out a need a new left side (drivers) rear frame rail, is gone right where the leaf spring connects behind the bumper. Now my question is.. is it road legal to build your own frame rails and weld them in? using the proper thickness and shape of coarse. Because I am having trouble finding a frame rail and i'm thinking I would liek to replace both while im at it.

Where I live it is legal. But, I would keep searching. I believe Year One now has reproduction rear frame rails for your car as well as some other restoration parts suppliers. Also there are quite a few good used rear frame rails to be found. Making one would seem very challenging to me.

OK everyone, my frame rail came in last week, now I know I need to brace the body before removing the old rails, I have an impact air chistle available for my use, will this be ideal for the spot welds holding the old rails on?

I would not reccomend using a air chissel. It will leave a jagged hole that is impossible to work with. I would reccomend a spot weld cutter. Simple to use with any drill. Basically its a hole saw for metal and leave you with a clean hole you can do a plug weld in and grind down. Looks just like a factory spot weld when finished properly.
