Hey guys, I'm needing to source a sleeve for an 8BA that's at 3 5/16" +.030 or 3.342" as I can't source one locally.

What's the best source, I have all the necessary dimensions.

Thanks !

I've bought sleeves from Rockauto before now. There are 2 thicknesses, the thicker one would take a + 30 bore. The thinner one might too.

When I need engine sleeves I always use LA sleeve.

I have NOS 11-a sleeves that seem to be the "thick" ones. Have no way to measure them.
