Hi,
I have a 76 J10 with a 401 motor and turbo hyrdamatic box. Can someone tell me the O.E.M. starter motor part number as it came fitted with a 9tooth (6 Cylinder?) starter which has chewed up the flex plate. The flex plate appears to be a finer tooth setup, perhaps 11 tooth also the original starter did not full engage the flexplate and chewed the first 1/4" all around the flexplate. I have fitted a new flex plate but don't want the same problem again.
I imprinted both the flexplate and the starter pinion onto a piece of paper and both measure different distances tooth tip to tooth tip when I compare them.
Thank's
