Hi guys, I've got my motor out for a rebuild and my stock mount on my aluminium arm has snapped off, so I've decided to use two steel arms. I've tried searching but couldn't find anything. Has anyone got dimensions of polyurethane mounts so I can make my own? Thanks!

You want them about 3" in diameter and 1 7/8" tall. A bit shorter if you run an oil pan brace. Be careful with generic polyurethane. There is a big difference in price and quality. Poly is tricky to cut straight. I recommend freezing the material first and using a high speed chop saw with a high tooth count blade. You will need to put together some sort of jig to hold the poly stock stationary as you cut it. It also helps if you lube the blade with cutting oil as you make your cut. If you want a set I can cut you one for $155.
