my 99 I/S is gdo work on it is getting close to 100K miles and I wanted to be ready for teh dreaded ujoint failure.
When I found out they are now on backorder I took a suggestion from here and contacted a Trike shop to see if they had one from a conversion that I woudl as a just in case.
They did - for 50.00 - I wnet down to Trikes by Coach Rice in Loganville, Ga and picked it up - walked out 300.00 out of pocket - turned out they also had the swing arm, axle, final drive, wheel , tire, brake caliper, rear shocks - so it has been added to my just in case pile

Anyone in the Atlanta area wanting take off parts they are good place to go to. Also they have some very nice trikes and even a few 2 wheel valks for sale. (I wasn't allowed to look at them too closely - wife was wanting to get back home and go for a short ride on her new 07 Shadow)
