Walt2103, first you need to measure the depth from the Starter mounting surface to the Ring Gear (flexplate) there are two types: a) with 3/8"(10mm) depth and b) with 3/4"(19mm) They are not interchangeable!
And please tell me which parts are new??? Did you change/replace anything since it worked the last time???
What about the Sheet metal plate between your 351c and the Transmission, is it present?
