[QUOTE="Woody6799, post: 14780635, member: 124316"] I am looking to compile a list of bolt sizes for everything and everything related to the IRS. Since I have my IRS down for powder and bushings I am replacing some of the bolts due to age. I am personally replacing certain bolt with 12 pt SS ARP hardware. I am hoping we can compile a full list here so it can be searchable later. Any one want to add to the list and I will update the first post. Diff Cover Bolts: 5/16-18, 1.25", ARP Kit #612-1250 (2 packs) Thanks to Rich'sTRsvt below and FTBR... Subframe-to-rear bracket bolts - 12 x 1.75 x 110mm - 18mm - 76 ft-lbs Subframe rear bracket-to-body bolts - 12 x 1.75 x 35mm - 15mm - 59 ft-lbs [COLOR="#FF0000"](ARP Kit #: 765-1003)[/COLOR] Subframe-to-body bolts 12mm bolts - 12 x 1.75 x 110mm - 18mm - 76 ft-lbs Subframe-to-body bolts for replacement Grade 8 9/16" bolts - 9/16" x 4 1/2" - 13/16" - 145 ft-lbs Subframe-to-body bolts for Ford 14mm replacement bolts - 4x2x110mm - 18mm - 131 ft-lbs NOTE: OEM front 12mm subframe bolts need to be upgraded to 9/16" Grade 8 bolts with Grade 8 nyloc locking nuts. Rear subframe bolts need an untheaded lead on them to guide the floating nut onto the thread to prevent cross-threading.
