The Quaife or any diff needs to be professional installed by a diff specialty shop since backlash and other adjustments are extremely difficult without the proper hardware. Once you have the diff sent to you, dropping in the pumpkin isn't too difficult and any shop could do that for you in about 2-3hrs labor max.

Yeah, I'm going about it backwards. I want to change up the sound a bit on my car but I don't think I'm going to spend $$$ on new exhaust so that's where the intake comes in. As for the springs, just going for the better look when I get my new rims and tires. How much quicker is your car in the quarter mile?
