Proper Distributor for HEI Conversion

"Can't remove the cap????" How are you supposed to set the timing????

For info, tho, ALL traditional Chrysler built single point or breakerless (aluminum housing) distributor DO HAVE some vertical play. I don't know what you mean by rotation, is it sloppy? side to side? or too tight?
It's hard to describe...it's almost a clunk as you turn it by hand.
