it looks like it has a few miles on it for sure.

the ring had a number of cracks in it and it came out in 3 pieces.

thanks for the info on the parts. I used a machinists ruler to measure the bore and stroke (Don't have my mic or calipers here) but I dont think it was as small as .74 or .78 based on the crude measurements....

I'll give Frank a call and go from there...

thanks again!
