1967-1972 Frame / Body Mount Dimensions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

graham1 · 02-05-2018, 08:53 PM

I have seen a few other threads, but haven't found a solid answer. Apologies if I am missing it. I have the service and overhaul manuals for '68 and they have dimensions, just not the ones I need. Does anyone know these or have a currently unoccupied frame they could measure?

TIA

EDIT: Looking for the red line lengths

I have a 68 short box frame sitting in the yard bare.Do you want center of the cab mount holes? Will try to get in the morning snowed here quite a bit last night.

Hole centers are perfect! Very much so appreciated! I'm on the road the rest of the week, so whenever is easier for you. Thank you!

Little tough to be exact by myself.I would have to say 57 inches give or take a 1/16.I measured both ways.Let me know if you need any more.

Those are the diagonals I assume, do you know the widths?

I just saw you're from Rochelle, my Moms half the family is from Mendota, small world

That was the diagonal measure.I will get you straight across in the morning.Just getting dark here now and i just seen this.Are you checking for a bent frame?That's why this frame is in the yard bare. Bought a truck half torn apart.Got it home started doing some measurements and found a bent frame.Once i got it torn down and measured it was pretty obvious.A simple job turned into a project. This 68 frame is going under my 70 hopefully this spring.

I started building a 68 on a non 67-72 frame several years ago. Just now getting back into the swing of things. I can set the cab square as I can but these numbers would help, I obviously didn't save any measurements from the original frame years ago, live and learn

The front cab mounts are 41 and 1/2 rear is 37 and 1/2 that is from left frame rail to right frame rail straight across.That should get you close.Good luck on your project.I might start a build thread on mine if i get my arse in gear this year.

Thanks! That was a big help.

And yes, start a build thread, would love to see it
