I am looking for a 200R4 with the BOP bell housing bolt pattern. I like to find out if GM made any 200R4s that have the universal pattern. I know some later TH350's came with the universal pattern (shown on the photo below on the right). http://www.texas442.com/TH350.JPG So do 200R4 with the universal pattern exists? Thanks Ali Austin,TX
As the previous replies indicated, the most common configuration is the dual bolt pattern bellhousing. You'll also, on occasion, run into a BOP only bellhousing as well.
