Hi everyone. Somehow I misplaced 
the 4 bolts that hold on the fan clutch/water pump pulley as well as the 3 bolts that hold on the crankshaft pulley. Can anyone tell me what size they are so I can go out and get new ones? Thanks in advance!

John, they're about this long, and this big diameter.(can ya see my fingers?

The water pump pulley/fan takes studs, with nuts on them. Studs go in the pump, then the pulley and the fan go over them, and the nuts secure the whole mess. (There are also lock washers there.) The studs are normally fine thread on one end, and coarse thread on the other. Should be 5/16" size, tho. Check the wpump to see if the threads are coarse or fine thread...I believe they should be coarse. If you go to a parts house, they should be able to get you the studs/nuts for it.
The balancer is fine threaded, 3/8".
(all SAE...no metric)
