If you are going to install the new fleetguard enviroguardthis is what I run into. A call to fleetguard after trying ever thing on TDR . I was told to remove the power stering pump, all wires that are in the way. When drill a small hole into the plug and install a screw in hole. A sliding hamer would have been nice put a punch under the truck on the screw work ok. With plug remove still had to rem out top of whole to install tub. About 4 hr after trying ever thing on TDR. day and haft all told. The most I have ever work for a free gift from maymadness. Hope it works. H Anderson
