could anyone point me in the direction where I could find the bolt size that bolts my clutch to the flywheel on a 77 351m 12 5/8 bolt circle. it has a np435 4 speed behind it.
Not that this is very much help but! Ford used 2 different ones 1" ford flywheel & 3/4" long for auto flex plate..Sorry that as good as it gets from my book about it.

Thanxs guys. where can I get those? does it have to be a dealer or can I get them from a fastener place? its the only thing holding it back from being drivable, its driving me nuts I need a mud truck!!!!
There are also aftermarket alternatives. The real auto parts store around here had a set of Mr. Gasket pressure plate bolts and lock washers (Part # 910) for me when I was trying to get my manual trans swap finished on a Sunday afternoon. I think they are listed on the package as Chevy bolts but they are the right grade, length and thread. I originally bought a package of ARP pressure plate bolts listed on the package as being for Ford but they were 5/16-18 and did not fit my application.
ARP also makes them and they can usually be found in your local speed shop. Be sure to get the right size and thread.
