distributor moving around help please

I guess keeping the camera still for more than five seconds was too challenging.

actually yes, the video was like 2 minutes long

i checked the bushing before installing the intermeiate shaft permanently and didnt noticed any breaking it might be that it just weared in seconds because of the "reaming"... when i say i hammered it i mean i used an old distributor shaft to hammer the shaft it in with a small wood hammer head that has no handle and then turned it by hand to """""ream it"""""" its not like i used a mallet to drive it in.

i also checked the slot, its clean but there is a little side to side play with the distributor tang is this normal??
