Is the spool mount k-member worth modifying/reinforcing and what should I change on the suspension brakes?

Reinforcement plates welded to the bottom of the lower control on? That could be done. As to the key frame itself, I’m not really sure. I’ve never had an issue with them.

Perhaps check with Mancini for bushings to see what’s out there. I’m sure they’re asking top dollar, but, at least you know if they have them someone else does.
