I got a real education doing this for my quicktime r5 bells. Turns out everyoNE of the aftermarket bells are wrong. Mopar is not .500". Industry bores holes to .501-502". Look at the drawings. My first bells came that way. New one's are .497-498" for the .496" mopar dowel. The aftermarket says so what. Well if you don't mind being. .004" low to start ok. The dowel not the clamping of the bolts maintains center.

There is a fix determine the amount that of offset and figure the .004" into it. Then buy .500" dowels from Robbmc. Take dowel and put in drill or lathe. Emory cloth will quickly cuto the engine side to .496". Hopefully my raising Cain will get the aftermarket to correct their drawings. Trust me they are hard headed and know everything.
