What engine? For a 300-340 or 350 SBB, the following is good info taken from the 64-65 SBB manual trans info thread: I did some measuring and found some ARP bolts that work for the flywheel to crankshaft and presure plate to flywheel. I have attached an image with the part numbers I used. This should work on a 340 or 350 as well. <FIELDSET class=postcontent><LEGEND> Attached Thumbnails</LEGEND> </FIELDSET>
Well I can't answer for the 455 engine, but I just ordered these 2 bolt kits from Summit Racing and it was $27.00 shipped to my door. For reference, last night I measured the thickness of my new NAPA 350 SBB flywheel, and it's 3/8" thick at the mounting bolts. Don't know if this would be different for the 455, I doubt it but how about measure your flywheel at the bolts so see if it's the same? Then you'd know if at least these flywheel bolts would work for you. The flywheel bolts come with washers too.
Double check the length of those to ensure they're not too long. The ARP bolts I put in my Nailhead were a little too long and bottomed out against the block when I was torquing them down. Touched them up on a grinder for a perfect ft.
