If anyone wants to machine their own "crank centering ring" Here are the specs of old crank bores and new crank bores. The pre 67 cranks had a CCR or 1.962 and the 67 and newer had a CCR of 2.157 (as listed on a few sites) so if you get an urge to put an early trans/convertor behind a later motor, and want to machine your own, or have a job shop run 10 off for you and your friends here on FABO; Have someone machine you a .195 thick ring, OD 2.157 and an ID of 1.962. Or you frugal types can get a few #9 (.196) drill bits and chop them up into 10-11 roller bearings of about .5 long and stuff them in there to make a tight .196 roller bearing thats not going to need to rotate. Hit either side with a file and you can whack off the .001 easily.
 
Of course...$38 delivered is fine. Im just giving the specs for a DIY'r.
 
Very nice of you to post that for every one!
