what are those things anyways? some sort of tricked out dust cover for the balls? i can't see where they'd be anymore of an alignment thing than the dust cover Bs that for the longest time i figured they were for some stabilization or something.
thanks for the replies, what i ended up doing was after trying to get the brass caps off of another spare (junk) rack and they were on so tight, i said screw it and just put the stripped one back on. someone (probably me) the thing so tight that 1.3 mm of the top aluminum threads were stuck into the cap and powdered. so loosing that much i only had 2 threads in the thing, i was gonna put a washer in and then drill a hole for a cotter pin. and then it dawned on a passing brain cell to cancel the washer, and add some aluminum foil folded 3 time and the length to just wrap around the threads with 1/4in overlap, but it wouldn't stay on, so it was time for the shot in the sync arm with jb metal weld to spread thin around the threads to hold the foil on, then the nut screwed on excellent. so now see if they work. i got to put some flat bowls on it so that seals, the connector tubes should work, only part about the set is #1carb main jet tower is eroded in a spot that just about exposes the oring.
