Frame hole Measurement help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Flashy2003 · 02-05-2022, 04:29 PM

I have a 68 Short bed C10. Originally the truck was a step side but I am going to a new fleet side. The problem I have is the frame does not have the holes for the rear cross member. Can anyone help me out with some measurements? I don't have the bed sides yet but I would like to get the holes drilled so I can start mocking up the bed floor. I would like some measurement from the rear of the frame to the front and back of the hole,some measurements from the inner and outer of the frame and a measurement from a reference point on where it belongs from another hole or mount in the frame. A picture with a tape measure across the area both ways is all I really need. It would be really appreciated.

My eyes could be deceiving me but it looks like the end of your frame has been cut off?

That’s exactly what it looks like to me.

I believe you're right . Looks like the rear crossmember has been moved back to accomodate a rear mounted tank.
If clearance is not a problem one could porbably get that hole drilled though.

Yes, the top was cut back for the rear crossmember "previous owner". But the sides and bottom was left stock I believe. So I definitely think I have enough room for a new hole. I just dont have anything to go off of.
