I installed a Manley roller timning set in a 6.1 hemi. It seems that I'm unable to seat the damper completely. The damper goes in all the way, and contacts the oil pump drive/spacer but the pulley seems to be out of alignment by about 1/8". It looks like the sleeve/spacer that drives the oil pump is thicker/longer than stock? Anyone experienced this problem?

If anyone has one of these timing sets uninstalled I would like to get the measurement for the thickness of the crank sprocket and the oil pump drive, so I can compare to the stock set I took out.

Thanks in advance.
