Searching for correct flexplate
I am looking for a new flexplate (old one's missing teeth)
I have a 1966 LeMans but a 66 389 GTO engine installed. Trans is a TH400. Looking a the dimesnions this plate should be the right fit: https://www.summitracing.com/parts/pqx-1845501 https://store.prw-usa.com/1845501-po...nce-166-teeth/ What confuses me is that it says "67-79" - can anybody explain that? Did something change on the crankshaft between 66 and 67? Why wouldn't that plate fit on a '66? I can hardly find anything on crank bolt patterns on Pontiac crankshafts so I assume that pattern never changed? The dimensions I measured on my engine are: crank register: 2.75'' crank bolt pattern: 3.79'' converter pattern: 10.75'' 166 teeth Thanks! TJ Last edited by Dailydriver; 06-16-2022 at 05:07 AM.
