1950 AD Truck Cab Mount Floor Hole Locations - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What are the measurements between the holes (center to center) for the holes in the floor for the cab mounts? I am replacing the cab mounts and the floor was previously replaced and i think the holes drilled in the floor might be off. The old mounts were rusted out in the area where the old mounts sat so i can not use them as a reference. My back two mounts/floor area is perfect. I was looking for the dimensions from hole to hole for the front to front, front to back on both, and diagonally from back left to front right and so on.

Thanks.

I would verify these measurements with someone else. I have my cab up on the firewall and it blocks all the light in my tiny garage lol.

From the front mounting hole to the outer rear mounting hole I had about 36 1/2 inches. Between the front mounting holes I had about 47 inches.

Would any of the manuals have these measurements?

A factory assembly manual will. Or you might try the old car manual project site has dealer tech reference manuals that have frame dimensions.

I couldn't manage to find where i placed my assembly manual but those measurements match up with the plans i have for a body dolly that uses the mount holes and matches up with where the new front mount holes are on my cab.

Thanks.

Factory assembly manual for the front mount on a '54 is 23.5 +/- 0.062 from center line so I'd say he's right on the money!
