When swapping over sensors and linkage, discovered the casing was about an 1/8 of an inch thicker. No biggy, found a different shift kit and with a little redneck ingenuity made it work. Very firm shifts. Recommend getting new tq nuts as ours were old and worn out. Also, if you don't install right away, open it up get your paperwork out and send in your warranty info. We didn't so now we're crossing our fingers. Overall really happy with our purchase.
