ARP 245-0901 Bellhousing Stud Kit for Chevrolet. Chrysler KB Hemi. hex ymm_60 however it fits both versionsThe engineers at ARP spent quite a bit of time developing these highly effective, unique oil pan studs. Theyre designed to make it as easy as possible to install a pan and seal it properly. Youll note that the studs have a radiused bullet nose that serves to locate the pan rails, then allow the nuts to be easily installed without the worry of cross threading. For those who prefer bolts, ARPs got you covered, too. Specifications Socket Size(s) 7 16
