hissonut1, have you found your bell housing yet? I am not fully up on all of the details of the flatty 6, but it sounds like what you are looking for is the bell and starter plate that would mate a '39 V8 tranny to a flatty 6. It is my understanding that the '39 style transmission was used through '50. I have read that the G series 6 ('47 and earlier) came with a transmission that was different than the V8. In '48 the H series used the same tranny as the V8. So if I understand what you are looking for, you want a '48 to '50 bell and starter plate. If I am correct with my assumptions here, I know a guy who has an H series I6 with a heavy duty 4speed behind it that he would part out.
