Size of holes for Cab and Rad Mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I need to fab up the tops of the mounts for the Rad (x2) and Cab (x4) due to rust and the holes being worn larger...I wondered if anyone has their frame exposed if the could tell me the proper size of the holes and how far they are from the outer side of the truck on centre please..Thank you!!

Around 13/16 for the rad support. Unfortunately the other side is a bad home made mount, therefore I can't give you an accurate center to center measurement.

For some reason the picture didn't stay in my last post. So if this happens again the front cab supports are 1.34 diameter and are slotted 1.68. The center to center measurement is 40.83".
Rear mounts are 1.04 diameter not slotted and are 42.16" center to center.
These measurements are for 63-66.

Note that on the drawing, ONLY the passenger side cab mount is slotted. The driver side mount is a 1.34" ROUND hole.
