Hello All,
Looking to see what the difference in thickness of the 69 and earlier440 steel crank dampner versus the OEM 426 HEMI. I bought a set of 69 and later hemi pulleys. MY 426 HEMI has a 440 steel rotating assembly, hence the thinner dampner. I need to fabricate a spacer. I bought the spacer w/bolts sold by Hoovers Auto, but it is too thin.

Thanks again for all the help on this latest project of mine...
