I pulled my old unit, pulled my terminal block and wiring and went to work.

I swapped pulleys using a 12V digital impact I picked up at Harbor Freight (sweet tool!!!), I then proceeded to mount my nice new $14 junk yard alternator (it is nearly brand new), its definatley bigger than the stock one but it just clears enough to get the belts on. I used a brand new adjuster bolt because my old one was shot and broke off (too short). I also used a new MB OEM terminal block that was all clean and shiny. To connect up the alternator I tossed the original cable (but I did keep the blue wire for the battery light).

I bought a 19" "Duralast Gold" 2 Gauge hookup cable at autozone for $6, works perfectly, and is extremely excessively overkill. I hooked it up to the alt and terminal block, put a new end on the blue wire and taped/zip tied it along the main wire, and hooked up everything, did a double check, and fired up the car. Way more juice! I love it! It can overcome my glow system at low idle and keep about 12.5V instead of 10V, above 1000RPM it will hold over 13V with EVERYTHING on. With a normal load (blower, radio, lights, etc) it holds 14V solid, even at idle.

Awesome improvement, and it was only the 80A unit! Those extra 15A really help!
