poly or rubber spool motor mounts

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.
