poly or rubber spool motor mounts

bbab3 said
The main problem I had was one just keep falling out of the factory bracket. Also they are way to tight for the bolts and did not fit into the K member well. I have run both poly and solid mounts in offroad cars for years. The noise was the biggest issue with solids along with metal fatigue of the chassis mounts, polys helped to a point. Obviously a street car is a different beast. What brands poly and rubber mounts do you recommend?

i forgot to mention I am using Doug's headers and have the '67 steering column with power steering.

I'm just using these ones from Energy Suspension. Pretty much all the poly stuff I run is from them, all of it has fit and held up well.

I definitely didn't have any issues with the inserts being loose, as I said before I had to "press" mine in with a bench vise. But the mounts themselves can vary a bit. I use poly grease on the install, so I haven't had any issues with noises and they've held up well. They will transmit more vibration than rubber, but the rubber seems kinda sloppy and the reproduction rubber seems to be pretty short lived/poor quality these days, especially the stuff that's been coming out in the last couple years.
