Going through my Model A powered hot rod and replacing stuff. Pulled the engine and replaced the SBC rubber in the front B mounts. The 17 year old F-A-M rubber mounts were as hard as my ex-wife's heart! Ordered new rubber from Bert's. The new rubber biscuits 1-1/32" thick and the original biscuits were compressed unevenly and measured between 7/8" and 15/16".
I wonder if those that are having issues with F-A-M have considered the fact that they may need to replace the rubber.

I replaced mine this summer, I used nyloc nuts on the bolts through the biscuts so I could set the tightness for what worked best. The engine was the most smooth with them loose but made the clutch jumpy. I tightened them down a little at a time to find the best trade-off.

Clutch chatter is fairly common in Model A's, even with stock mounts. Model A's ARE what they ARE!
