The holes not lining is not the real problem, The "snout" on the 4L80E converter is not long enough to engage into the crankshaft.

This is what GM uses to mate a 4L80E to a LS engine http://www.gmpartsdirect.com/results...umber=12621399 & the only Flexplate that I know of that will work with your 6-bolt converter

Heres another thread on the subject http://67-72chevytrucks.com/vboard/s...d.php?t=426994
