how do you remove the wire clip on the shaft to remove the tee bar?

I assume you spred it open??

I think I am going to try to install the mech advance limiter plate from FBO?

I picked up a new re-man points dist for 30$ to ge the truck running.

I have the Mr. Gasket advance cure spring set and it looks like you "JUST" drop the plate on the right holes.

looks simple enough I can do it.
