Proper Distributor for HEI Conversion

I don't like the way the distributor rotates and vertical clearance is too loose. Because you can't remove the cap to investigate without voiding the warrantee I am sending it back to RA for a refund.Fail I guess.Will stick with original points distributor , ect. 'til spring and then figure out what to do at that time.

"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?
