Well, the SYE I ordered was a problem. Apparently, there are not many out there that are available. I used NorthRidge to order then called when it did not arrive in a reasonable amount of time. They weren't even going to get it in for another couple of weeks. I cancelled the order.
I called around and found one in Denver at 4-Wheel Parts.
I installed it this weekend. I removed the spacers from the
transfer case skid plate and cinched it up tight. I still need to reweld the axle perches, but I am going to design a jig so I won't need to use a shim at all. I will need to move the axle forward (as it is hitting the fender flare).
I will take it in to a local drive train comapny and get a custom rear drive shaft manufactured for it.
I hope to have the Mighty YJ on the trail again this weekend!
