how do you replace a sub frame and the inner wheel walls on a 1989 pontiac Firebird?

[warriorhoc8]

I have a 1989 Pontiac Firebird. There isn't anything mechanically wrong with the car. However the body is rotting. I already replaced the floor pans and the front quarter panels. I was wondering if there was any one out there who has a firebird and they have done the complete body and sub frame. Thank you for taking your time and reading this and responding. any answer will help.

It is a labor intense job, only a body shop should do as the entire frame is tied to the wheelwell areas of the front chassis ..
any misalignment or improper welding could cause the car to become unsafe ..
in this case if the damage is too wide spread you may want to part the car out and look for a solider chassis ..
