ive grind down the rust surface to bare metal on my 89 gta now im looking to weld in my hotchiks weld in sfc how hard will this be ive also got all the interior out an all the gas lines an brake lines removed to do the install process which weld will hold the sfc in place so far they are bolted into the k member in the front an also into the rear slot where the rear lower control arms bolt into the car now just need to weld in place now

 

It's not hard, pretty straightforward...

Main thing is to make sure that the chassis is ABSOLUTELY STRAIGHT. Once they're welded on, they will try to hold it however it is. People talk about "suspension loaded" but that's not necessary at all; you can support it any way you want, AS LONG AS IT'S ABSOLUTELY STRAIGHT. Mine for example were installed on a race car jig, with no suspension or K-member even there at the time. You can use jack stands, a lift, alignment rack, or any other method, AS LONG AS IT'S ABSOLUTELY STRAIGHT.

Did I mention, make sure the chassis is ABSOLUTELY STRAIGHT? In case I didn't, make sure the chassis is ABSOLUTELY STRAIGHT, because you only get ONE SHOT at it.

 

i have the car up on jackstands now an do u mean the rocker panels have to be straight or are u talking about the whole car

 

Whole car. If I was you, I'd most certainly wait until after you've got rid of all your rust and properly repaired all the structural steels: floor pans, rockers, front & rear subframes, rear seat pans, trunk pans, inner wheel houses, any any other steel minus body panels that joins to the chassis before I weld in SFC's of any kind.

 

ahhhh ic looks like ill be asking my buddy to come back over to do more rust repair then where can i order rocker panels these days does hawks sell them or classic industries

 

Neither. Classic sells the outer skin skin only. The actual structure of the rocker needs to be cut from a donor car or ordered through a body shop. It'll run about $150 for each side to get the new steel.

You can't weld in new floor pans or SFC's without fixing the rockers first. The rockers are what tie the pans together with the front & rear sub-frames.
