The job went smoothly enough and no more oil leak! I'm very happy with the progressive springs. I went with 7 1/4" spacers. Dealing with the brakes showed me that my next job should be to thoroughly clean them, bleed the system, and then refill with fresh brake fluid. When I turned the wheel after putting it back on I noticed the brakes dragging against the rotors. I've read that some dragging is normal but since I don't have any previous experience with bikes (or any kind of mechanics for that matter) it's hard to tell if what I'm getting is too much. Hopefully, cleaning the calipers will loosen the pistons and allow a little extra clearance for the pads on the rotors. Anyway, thank you guys for your help. This forum rocks!
