Thanks Fred,
And I checked for wobble with the synchro rings and found none. That either means I am okay, or the brass part is worn down so much that it fits perfectly. There are a few divots in the upper (non-wear) portion of the rear synchro ring. Looks like it took a hit from one of the gears at some point.
I did see a set of NOS synchro rings on eBay, but the drum seems scarce. I am hoping that I don't need it. Already up to about $500 on this rebuild. Does the brass part come loose from the rest of the drum or is it one integral piece?
I appreciate your input.
Jim
