I need new motor mounts. After doing my clutch, I became aware that the rubber in all the mounts is all cracked and dry rotted, thus making my whole engine knock and move alot.

I think I seen a DIY here where someone rebuilt thier's with some rubber material that they poured into the mounts, and made them one piece.

The motor is a D16Y8 (for now until I finish my K20a) with a 5 speed tranny.

Where to get some quality motor mounts?
