Motor Mount thickness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Tried this in the "Drivetrain" section without luck...

I have a '69 Fleetside Shortbed with a Gen 1 SBC and I'm using Prothane Motor Mounts (the kind with the single bolt coming from the bottom of the tower). They are 1 1/4" thick from the top of the tower to the engine block.

Can someone tell me if that is the same as a stock motor mount?

I'm trying to dial in my driveline angles and everything points to my motor being too high. It's driving my crazy because I am 99% sure the towers between the motor mounts and the crossmember have never been removed or damaged. Truck has been in the family since new and I'm owner #2. Cant imagine Grandpa did any "surgery". It even had the original spark plug wires on it when I got it!
