Engine Question about bolt size

[Ahayne]

Where can I find information on bolt sizes? For the most part I know the diameter of the bolts I am not sure of the length. I am looking for the 4 bolts that attach the radiator fan to the engine and the bolts for Power steering pump to the engine? I have a 77CJ7 with an AMC 304 .

Hate to say this but depending on how your fan is mounted your milage varies. Over time there could have been many modifications such as a different fan or an additional spacer. This is where a tape measurer is probably best. Measure from the fan mounting surface to the water pump impeller face and add 1/2" or even 3/4" as there is plenty of clearance behind the impeller face as they are thru holes.
There were a few different power steering pumps that were used in that CJ era, so the same goes for the power steering. Measure and 1/2".
Curious as to why you need new bolts? What is wrong with the current ones?

I have misplaced the bolts.

Ok, that gives me a start. I think the FSM gives the lengths. I'll look today.
