I think it was the 88-91 fords that used the support system. The support system would be the tubes that bolt behind the front suspension. I agree with Dino unless your an great welder don't attempt to fab your own parts. Only some trucks are easier to fab mounts for then others, i have done it before and helped friends do it. On the 92-97 f 150 and 250 ld and up to 97 250 hd and up, the frame mounts from fisher were easy to make fit. It can be done just make sure you use at least 1/4 plate for your frame. I would have a support behind the bumper bolts, and your other supports on the frame just be for the front end.<p>Once i saw a friend of mine take the mounts for a 93 f150 fisher minute mount and make them fit a 97 f250 ld. He took the bumper support brackets and bent them down. Then he slid them into the fram box, and put a few 1/4 bolts in and called it good. The pump was even a bigger mess, it was a belt driven pump on a 5.4 v8. He had to cut the air filter case to make the pump fit. The funny thing is he hasn't had a problenm with his mounts or pump.<p>Don't try this at home or in your shop, unless you are a great with mettal or have a friend that is.<p>Geoff<p>
