Need advice

Just picked up a 68 LWB C10 Last month. It also came with a 72 LWB C10 complete frame.
I plan on doing a LWB to SWB conversion. The 68 was damaged in the left front and may have a slightly bent frame (I'll know more when I pull off the front end and cab).

Once I check the frame on the 68 and if it can be fixed should I use the 68 frame or the 72 frame?

Thanks,
Wess

Probably the 72. I think they have something better with the mounting for power steering. And disc brakes up front.

Re: Need advice

I didn't even think about the power steering, thanks.

Re: Need advice

I think it's only the '67 frames that may or may not have the dimple for the steering pump. As for the disk vs. drum brakes of the 67-70 vs. 71-72, that would be a steering spindle thing rather than a frame thang!

Re: Need advice

I was looking around the site last night and found the info for the disc brake switch. Looks like I just need to swap out the spindles and drag link items and I can use the 68 frame (provided it is usable). But if it can't be used at least I already have another frame.

Re: Need advice

Well got bored today so I pulled off all the damaged metal. Looks like the 68 frame is not going to be used. Too bent up.

Stay with the 68... if it is bent take it to a frame machine...

Re: Need advice

The choice of which frame to use depends on what you have planned for it.
The 72 frame should already have 5 lug axles front and rear. Your choice of available wheel styles depend somewhat on this.
The 72 already has front disc brakes. Much improvement over drum brakes. It may also already have power steering.
Or use your 68 frame and be out the expense of having it straightened and still have to move the 72 components over to it too.

Re: Need advice

If the '72 frame is strait I would go with that. Unless the body shop tech is good working on channel frames the '68 frame may never be right.He can get the pulls done to bolt up the sheet metal but the track of the wheels may not be right. I have been in the industry for more than 30 years and have had to repair truck frames that other shops fixed first. Not that many frame vehicles on the road these days so a lot of techs have little or no experience in this. Most cars are uni-body and trucks and SUV's are hydro-formed frames. Just my two cents.
