Regarding ride quality....its funny,... I actually think it rides a little better....silly I know...the front of the leaf spring "is" an inch longer....lol...
It changed my pinion vibration a smidge, as in lessened it, it was not much pinion vibration to start with, but I feel it, and moving the axle back some how improved it.
Drilling it was soooo much easier than I thought. I have a drill press, but when the pilot holes were so easy, I just continued to use my battery drill the whole way through.
I drilled small 3/16" pilot holes then moved up from there I think to 5/8" & 3/4". Wild Horses plates and pins are really big.
I just put 1490 miles on it going to Super Cel. Worked beautifully. My driveshaft was long enough, as it seems to stick out of the slip "maybe" a half inch or less further.
So it worked out great for me. I say try it. It is real easy to go back to stock.
