SOME waterpumps have a ridge on them that extends to the bearing end, and you can use a 3/16" allen wrench to catch the hole in the WP pulley instead of using the tool... however, none of my 87's have it.
most auto parts stores have the large strap wrench needed to hold the pulley still for 4.99 but you don't get the smaller sizes that the HF kit includes...
also, you don't have to order the entire fan! call Phil from the buy parts link, and order just the clutch if you need it, for less than 120.00...
