when i did mine i took step by step pictures of the 1990 SC Seal removal / Replacement. Very easy Job and it is as easy as it looks just make sure you get the Pulley off without bending it with a 5 Ton Puller
Yes, those are some high quality pics. Which camera did you use? Maybe this can get moved to the FAQs forum with a little narration explaining the parts' names in the pics for terminology sake.
It's expensive, yes, but totally worth it. I spent hours and hours trying to remove the pulley from my spare SC with a crappy 3-jaw puller with no cage. The cage makes all the difference. I got so fed up I went and bought this, and I wish I had done it sooner.
One caveat - I had the SC off the car, so I don't know how hard it is to get the puller on the pulley with the SC on the car. I can try this weekend.
Autozone has a free rental of sertain tools if you have one in your area. you basicly have to rent for the price they sell for and then whenever your done you just take it back to the store and get your money back. pretty cool service
