I have a 65 c10 short bed that ive been working on for a few years now. When it came time to put the bed and cab on I found that the frame was twisted for a previous wreck I suppose that I wasn't aware of before I bought the truck.

I found a frame for sale near where I live but someone has noched 2 inches off the top frame rails on both sides near where the radiator mounts and gear box.

Question is is it safe to go ahead and weld a piece of 1/4 flat bar and fill in the noches area?
Any thought appricated

I'm not an expert, but I've been told by people I trust that the old frames are not heat treated steel and therefore there isn't much strength lost by welding to them. There is some work hardening during the forming process, but that isn't very significant. Furthermore, the area you're describing isn't a high load area since it's in front of the front suspension. Its main purpose is to hold up the radiator. It's also significant in a front end collision for safety, but newer frames are designed with crumple (weak) zones in the front, and weakening the frame in front of the front crossmember might actually be beneficial in a collision.

Hi 504, What the other poster is probably referring to is High tensile steel rather than heat treated. I don't know how early this started but My 79 F250 3/4 ton has a high tensile frame.

How bad is tour original frame, as it is relatively easy for a good panel guy to straighten it on a chassis table. If you build cars for $$ you work out very quickly that checking this saves heartbreak and hassles later.

The areas you are talking about are low stress so a home welder could tackle them but a pro will do a near perfect job faster. Have you had either of them sand blasted to see what they are really like.

As you have clearly worked out a straight/strong frame is the foundation of any quality build.
