I have search for the past 3 hours and called Summit and ARP with now luck. I am putting a TF-727 behind an AMC 401 and need to know the flexplate bolt size and where I can find the reinforcing ring that goes between the flexplate and bolts. Any info would be appreciated.
bolt size is probably the same as the flywheel bolts. might even be the same as chevy or ford. take a tap set and find the one that you can thread in by hand.
I have the old flywheel bolts so I know the threads just need the length. It is either .680 or 1/2 long. I think the reinforcing plate is going to be the bigger issue.
Scroll down in this thread about halfway and there's a picture of a pile of misc. parts for sale with some flexplate mounting bolt rings in the upper left corner. Looks like there is more than one type there, not sure which type you're looking for, seller is 71SC360 in New York I believe.

I see 3 of them. I will PM him. Thanks
Use the 1/2 inch length bolts. Any longer and the bolts might hit the block when they come out the backside of the crank flange.

I ordered the reinforcing ring from 4wd.com and only 4 of the 6 holes line up. The flexplate is good, but not the ring. Not sure where to go from here.
The Flexplate / Crank / Boltring Pattern aligns only in 1 position.
Sure it is clocked correctly ?
The 4 Torque Converter to Flexplate Bolts are the same way.
All 4 line up in only one position.
Best to determine where that is and mark parts before mating engine to trans.
If misaligned, converter will not rotate 360 deg with trans bolted to block.
The tapped pads on the converter with hit the flexplate balance weight.
Both of these is because the Flexplate is part of the engine external balance.

I rotated the ring a million times. It just doesn't match no matter what. I made sure the flexplate did and the torque converter to the flexplate, but the reinforcing ring won't mate at all. Not sure what to do from here. About to uni-bit the other 2 holes and make it work. I wish I could say too much beer, but thats not the case. I will try and take a picture and post it.
Was it flipped over and tried using the other side ? iirc only one hole is "off", but not sure.
