THANX for the responses, guys! I haven't found an aluminum(?) Ranger bumper, but I'll keep my eye out for one. The thought of making a mold for a fiberglass version sounds like it's way over my pay grade! I was really hoping that I'd be able to find a mfr of fiberglass body components that still had an old dusty mold stashed in the corner of their warehouse, lol.
As for the "gasser style" tube axle, it's only in the "Imagineering" stage at this point and hasn't been implemented. BUT......I've been kicking around the idea for the past 15-20 years (long before I acquired my current Ranger). As many know, Ford engineered and implemented the Twin I-Beam suspension for introduction in their 1965 F-series trucks and carried the design over to the Rangers when they were introduced in '83.
I'm essentially an old drag racer, hence my desire to cut weight from the truck......with front-end weight being the most critical. As most of y'all know.......weight reduction yields virtually the same result as adding power. And.......in spite of some folk's apparent liking of the Twin I-Beam setup (19Walt63?)........I've always hated it. Not only for its' wonky tire-scrubbing suspension travel, but also for its' heavy cumulative and unsprung weight. A gasser-style tube axle with twin leaf springs may or may not ride as well, but at least it will maintain consistent camber and toe, AND it should result in a dramatic loss of weight.
Two smallish utility-trailer leaf springs (got 'em) and a tubular solid axle will replace the two forged-steel beams, both radius arms, 2 heavy/elaborate cross members, plus both coil springs & their mounts. Obviously, I'll need cross members to support the engine & trans....but smaller/lighter tubular versions should get the job done nicely. 40-Ford spindles (have 'em) are much lighter than the Ranger versions (which also require two ball joints each), AND the brakes I'll tentatively be using (from Speedway) have thinner non-ventilated discs and aluminum calipers. Also, two Chromoly tubular tie rods should be a lot lighter than the forged-steel drag links they'll be replacing. I'm hoping for a 100-ish pound total weight reduction, BUT.......we'll see! <shrug>
