Hopefully this is the right topic to post on. I want to know the gauge steel the front subframes and the crossmembers are on the 68-70 b-bodies. I plan on patching the these parts. I have a welder, gas, and mild steel to bend.

This is the subframe on the passenger side. I guess I should replace the whole subframe with a new piece. Or should I fabricrate. I think I have to take the motor out and the fenders and hood too.I think it is 16 gauge on the substructure, but it could be closer to 14 gauge. 16 GA is
.062 and a half thousandth. If you have a 0-1"
micrometer, you can get very close on a measurement.
I was taught at penn tech. Keep the gauges the same and weld the new metal into the old metal. If your angle is from old to new you will burn the old metal more easily.Ummm if I had to patch some frame rail places I do not think I would just use factory thickness metal but go heavier
In the past I have made the short section of frame that the rear springs mount to on a second gen B body
The torsion bar crossmemberYou are patching the K-frame ? What front "cross-member" are you referring ?
Replace the car imo. On my 73 Barracuda it started with the front frame rail ended up everything but rockers and roof. I only used factory frame piecesThis is the subframe on the passenger side.

Replace the car im
Exactly what I was thinking, but didn't want to be the first to say it. Don't think I would bother with that car unless it was something rare like a Hemi or A12.or a solid donor......but if the donor is solid, just build that one
Oof!!!! I would replace the entire frame rail. It is a pretty intricate area and that rust looks nasty. Inner fender skirts look good. Framerail and upper shock mounts are suspect.This is the subframe on the passenger side. I guess I should replace the whole subframe with a new piece. Or should I fabricrate.
