Where to get a 904 flexplate

Bill Dedman said

Thanks to Ryan, I got information that enabled me to order this:
http://www.jegs.com/i/B&M/130/10230/10002/-1

which is a B & M flexplate for a forged crank, internally-balanced, small block, Mopar engine. The crankshaft attachment holes are not a perfect match,but I think I'll only have to slot one of the holes.

I'll keep you all posted on that. The converter attachment holes are in 3 different configurations. One, is a 10"-diameter pattern, and that will fit the attachment holes in our converter. The Jeg's ad says it's for a 727 transmission, but the tech guy at Jeg's said it should work okay with a 904. I can't see why it shouldn't.

Charlie, what do you think?

Bill, pretty sure that one will work. You will have to "slot" one of the crank bolt holes. The outer holes are for the large 727 style converter. The inner circle of hole are for the 904 converter. The smaller 904 holes are for the stock size converter bolts, and the larger dia holes are for the "race" type converter bolts. Most converter manufactures can give you whichever size bolts you wish. I would reccommend have the converter built with the larger bolt size, since you have the provision for this on the flex plate. Opps, just noticed you have the converter, already. I will leave this info in the post for others.
PS: my converters use the small bolts, so it is not a major issue.
