No problem..glad to help..glad we seem to have a good alternative source.
I swapped the drivers side out cause I had torn two boots the previous day on Golden Spike
Didnt remove "green cup"...( not a Stoop job!!)....simply released boot from cup on new shaft...
....took out old shaft/cv's...and slotted in complete new one.
Only one side of one boot to secure, to green cup.. ( still a pain..and knuckle skin'er !).....
....but quicker in the long run .
I'll be servicing the OEM shaft I took out, re-booting it...
...and carrying that as a spare.
If I have any issues with the Surtrack ..I'll let ya ll know.
