Original bolts & u-nuts are difficult to remove due to rust and the type of threading used at the factory.
Ford uses self-threading tri-lobular bolts called TAPTITE2000.
The bolts are driven down with a special tool into a u-nut attached to the frame that is not threaded.
These bolts require the use of a T-50P torx plus socket (do NOT use a T-47 or a standard T-50).
Once the bolts and clips rust/oxide they are nearly impossible to remove and often need to be cut off.
Auveco’s replacement bolt and u-nut.
Standard threaded bolt Auveco #’s 25042, 25043, 25044 and mating u-nut Auveco # 25041 do not require the need of special tools.
Bolts follow the head and shaft contours of the O.E. bolt which allow them to duplicate the original fit & function.
