Front Cab Support Frame Mount - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey all,

On the cab support that is riveted to the frame, how large a hole should it have on top for the bolt to go through? I took my cab off along with the old crushed rubber bushings and found that one side has a 2.5" diameter hole and the other side has a 1.75" diameter hole. My guess is this was caused by years of rusting and rot. I think they should only be about .75" in diameter or maybe .5" to allow the bolt to go through and for small alignment adjustments.

Comments?
