motor mount question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

new to forums so bear with me.

I have a 69 gmc 2500 longbed fleetside. it came with a v6/4 speed. I am putting a 400 small block in it with t350. I am a bit confused about the motor mounts. The perches have a hole about 1 1/4 inches, obviously much too large for the bolt to hold onto. I found a rubber cube with a metal plate on one side that appears to go on the underside of the perch. The bolt goes through the rubber cube, through the perch and into the rubber motor mount on top of the perch (attached to the motor). Is this correct? if so how or where do I get new rubber cubes because I only have one. The setup is similar to the manual trans mounts but larger. Let me know if I'm way off. Any help is appreciated. maybe i need new perches with small holes?
