904 and B&M 10235 flexplate

because of crankshaft end play. the flexplate is still hitting the starter or something in the bellhousing. you said yourself that you had to modify the starter to get it to fit. you shouldnt have had to do that. the extra inch or so differance between the small bolt circle and the o/d of the plate is whats interfearing with your starter.the plate must be overlapping the ring gear by at least half.
