The ARP flexplate/flywheel bolt kit is made for Chrysler 440 engines and uses 7/16in bolts for attaching the flywheel or flexplate. It names the Chrysler 440 application and the bolt diameter, giving a direct hardware match for builders and restorers working on that engine's flywheel or flexplate fastening.
