Help! Stock fan blade bolt size on '87 S-15
OK so this is a crazy question and probably will require someone going to their truck and unbolting their fan blade, but I would be forever grateful........
Some idiot replaced the stock fan setup with a fixed aftermarket fan. I have a 2.5L 4-cylinder '87 S-15, so it's really underpowered, and I want to switch back to a fan clutch to gain some power.
I bought the stock fan clutch before I realized that it was an aftermarket fan blade, which doesn't fit the stock clutch. Here's the kicker: it's a different bolt pattern. I've found a new fan blade easily from car-part.com, but nobody has the bolts with the fan.
So......... how do I figure out what bolts to use? Does anyone have an '87 or '88 S-15 that you can pull a bolt and tell me size, length, etc.? Is there some way this can be deduced?
