My schedule has been very busy lately so the assembled carrier on the garage floor for a few weeks before I installed it this weekend. I cleaned it some and put a few light coats of the original paint back on the carrier to cover some scratches left from the machine shop.
The carrier is very heavy and it took a few times of lifting it before I was able to get it up and into place with the exhaust still installed. I used a new Fel-Pro gasket with a light layer of RTV. Additionally, I used a new set of copper washers and locking nuts. I was not as meticulous as in the past with cleaning up everything after the install (brakes, driveshaft, etc) but the job is done.
I sold the old set of 3.25 gears on eBay which paid for the installation of the new gears. No reason the have the 3.25 laying around as I do not expect to switch back.
