well, i do have an sfi approved flex plate with ARP 7/16 bolts...problem is....my aftermarket 3000 stall PTC converter has mounting tabs for a 5/16 bolt only....i shoulda checked that when i first got it, but i went ahead and used the stock stuff for now. i dont have time to wait to send my converter back to cope racing trans and have them install new 7/16 mounting provisions....
