deceptive gt Posted April 8, 2015 Report Share Posted April 8, 2015 I am trying to make the rear end in both my cars as stout as possible. My parts list for the GT are as follows: Eaton Detroit TrueTrac LSDFRPP 3.73 GearsFRPP Install KitStrangle 31 Spline AxlesFord Racing Diff CoverARP Diff Cover Bolts My question is about inside and the bolts used. I know ARP has bolts for the 8.8 and True-Trac. Will these bolts clear my Diff Cover? and hat is the advantage of upgrading the TrueTrac bolts?
