Engine is 258 V6 4.2 on my 73 Commando. I am confused about the crankshaft pulley and the harmonic balancer and what exaclty I need and what size/diameter. It appears that only the crankshaft pulley came unbolted from the damper due to no loctite was used. It is/was a single groove pulley with 3 moutning bolts. The damper and I ithink also the damper retainer and harmonic balancer is still there. I already bought a used crankshaft pulley that was supposed to work but it appears that the diameter which is about 7-1/2" is too big AND the three raised areas on the side with the timing marks is too small as it won't fit over the balancer. So I am trying to find out if someone can give me the specs for the one I would need that won't hit the fan and will fit properly over the balancer. so that it can be bolted on to the damper with the 3 mounting bolts. If someone can tell me the specs and if their are compatible pulleys in size that would work on this since Jeep Commando specific parts are nearly impossible to find. Thanks very much for reading this and helping if you have the info.
