Motor Mount Spacer

Post by jmcpherson »

The rear motor mount spacer is 19/32" long. What is the OD and ID? Is there any reason not to use a solid steel vs the original split steel spacer? THANKS

jmcpherson,
I don't find the information you requested (sorry). The ID will need to be large enough to allow the bolt to slide through (not a snug fit). The OD does not make much difference (it must be large enough to be retained between the mount and plate.

I see no reason that the tube could not be without a seam. The nuts would be tightened snug (+ enough more to align for the cotter pin).

I hope this helps
Regards, Neil Wilson

Chris, I can't find a photo of these small tubular spacers which keep the rear engine mount bolts nuts from compressing the rubber cushions. I found the A-chassis part number in a Steve Plucker document. The AA spacers were slightly longer due to the thicker AA frame side members.

What I have found on all chassis parts that relate to the car is that the bolt and or rivet kits sold for the cars are always too short because the truck frame is thicker gauge metal. Not exactly what you were asking but relates.
