you are right,

Back to RTABS: I was recommended AKG RED as strong enough for Stage3. But who knows? I always liked the sleeve concept but was told "no", install the "reds". Dont take my techs word for everything. See if there are other opinions.

I have good old Power Flex FCABS. But AKG recently has gotten better press over all for their poly mounts. Safe to say go AKG for FCABS. Red is probably just fine.

I would love to hear more about the differential and adding poly. I remember coming up with no options a year ago when i looked.

we pretty well have beat the motor mounts to death. Might as well talk about other mounts. Its good to have them all work together. I know I was told not to mix solid and other types of mounts on the diff.
solid diff to subframe bushings will increase the strain on the subframe to chassis mount points and bushings so it's good you've welded in the reinforcement kit.
