not the convertor bolts but the plate thta houses the 6 crank bolts?
Ken, that is called "scuff" plate by DD Bob told me today that there is a hub that goes over the end of the crankshaft, the flex plate and then the scuff plate and a DD should have that if not have the Allison parts guy look under remote mount transmission along with Allision Torque Converters and Twin Disk Torque Converters (these are not the torque converters on the transmission but a fluid drive transmission) good luck
Ken, I don't have a 71 series book but did find what Bob was talking about in the 8V92 book if you have access to a 92 manual it is on sec 1.4.2 page 1 that is what you need less the disk.Maybe someone here could post or email the page to you good luck
