LMC tranny/transfer case mounts for K10?

[Jimal]

How good are they? I think/I'm pretty sure I have a bad tranny or transfer case mount in my truck. I'm getting a lot of driveline movement on decel; the transfer case lever jumps when I come off the throttle, I get an intermittent driveline shudder when I release the clutch from a stand still, and I feel like I'm getting some yaw when I come off the throttle.

I have to assume someone here has used the LMC mounts. Are they any good? I need to order my next batch of stuff, so if they're worth the trouble I'll add them to the list.
