Steve, that aluminum adapter plate has caused trouble in the past for some drivers. It carries an internal plastic bushing that is supposed to guide the pushrod extension for the MC. Some bushings were sized too close to the OD of the pushrod, and when things get overly-warm up there, the adapter hole closes up, the bushing pinches the pushrod and your brakes drag- or lock. I fixed Russ Britschgi's Pantera during a Gold Country run about 18 yrs ago when that happened. I reamed the bushing with (what else-)a jacknife; the locking went away & has yet to return. You're looking for a sloppy fit, not a precision one.
