StreetMaster Performance and engine mounts

Does anybody know if they are still in business? I was looking through an old Mopar Action and liked their spool mounts to put a B motor in the early A with hipo manifolds.

The Schumacher spool mounts say they need a custom exhaust so I guess the manifolds wouldn't work with them?

Final quick question - are all the old style rubber 'biscuit' mounts the same dimension for all engines? Are big block ones stronger?

thanks

As soon as I noticed that Shumacker had them I didn't see that other company advertising them anymore. I'm wondering if Shumacker didn't buy them out or bought the design? I've delt with Shumacker on my motor mounts brackets and solid mount with a torque strap. I'd call and ask him if they would work with the manifolds.

yeah, I wondered if that might be the case. I guess I'll call Schumacher.
