Harmonic balancer bolts up to my 87 Wrangler w 4.2 engine with minor adjustment.
The pulley holes are not right on and will need to be made a little oblong for the outer pulley to bolt on. Went on extra tight and had to use the bolt to pull it up tight. Should have had a new moon key with it would have been nice. However it is on. Couldn't find one available that doesn't need the bolts to be a little offset.
