Has anyone run into any problems installing one of these? I have the 1158 ( March Performance 1158 - March Performance Fluid Dampened Harmonic Balancers - Overview - SummitRacing.com ) that I tried installing today and could not get it to pilot onto the crank snout no matter what I did. I even tried very lightly tapping it on with a block of wood and a hammer and couldn't get it on more than probably 1/8th of an inch, which wasn't anywhere near close enough to get the crank bolt in and draw it on that way either. And the instructions make it sound like it should just slide right on. It almost seems like the I.D of the damper is too small for the O.D of the crankshaft. I've never heard of anyone having any trouble with one of these. Thoughts / ideas?
