I thought you had an aluminum one, oh well, good to know.
The fact you need a T-47 bit for the install is super annoying
I did. A shop put it in and I had terrible deccel vibrations. The company told me to tried A) rotating the shaft and B) getting the the driveline aligned. My buddy and I rotated it 90 degrees and it still did it. We measured the pinion angle and I was pretty sure it was off. At the time, I did not have an adjustable upper. I had the shop take a look and they insisted the pinion was not off. I was ticked off because it was right before the first part of my board exam so I made them take it out and got a full refund. When I moved up here, I needed the bung done for the O2/Widebands so I had Dez put an adjustable in and Brian the installer showed me it was off. I had it rechecked at MPE and it is perfect now.
I will do a DS again at some point but the vibration issues are a big problem even with the driveshaft aligned. We'll see. Its a lot of money and plenty guys run without it. We'll see.

lol...never seen him/her
