I have a Pair..
When I had to locate these bearings, it was a PITA.. I swear it was 90 days of searching high and low taking micrometers to parts houses and literally taking bearings off the shelf trying to find an application that would work. Finally I found a guy in Australia who had 2 pairs, he wasnt keen on selling them to me because he was a wholesaler and didnt normally sell retail, second he wouldnt know how much to charge me for shipping and couldnt take a Credit Card Payment.. anyhow I finally pursuaded him with enough cash upfront to pay for the shipping and his trouble plus the parts. I bought the last 4 he had. Used one pair on the 68 and put the other pair in a droor...
Just in case
I still have the 71 in the back yard, so I hesitate to get rid of them... But knowing how hard these were to find, I wonder if there is someone out there that is in dire need.
PS...
Sorry for disapearing for so long!
