I tried to use some Toyota truck rims with something like a 205/75 x 14 rim on my HF frame. Although this is the proper bolt pattern for the HF heavy duty (5 lug) axle hub, the tire would have rubbed on the frame. In short you will have clearance problems unless you widen the axel or use spacers on the axel hubs. Widening the axel would require cutting it in half in the middle and welding a pipe between the two lengths, and it would require remounting the spring seats to a point further inward on the axel tube. Then you run the risk of over leveraging the axel and possibly bending it or worse. I thought long and hard about the modification and decided against it.
By dropping the sides down about 3 inches or adding a skirt you can hide the frame and lower the visual attitude somewhat without any serious mods to the original axel design. This requires building "over" your wheels. Another option would be to change the axel out for a dropped axel of some sort. The problem with doing to many mods on a HF frame is the mod costs can easily approach the costs for a different, or custom frame.
I also thought about changing my axel to go on top of my leaf springs, and last summer when I had it up on jack stands to grease the bearings, I noticed were the axle U-bolt had come up and kissed the axle to frame mounting perch. This is the part that most people notch when going to a axel flip (on top of the leaf spring) set up. So even with the axel in the stock location, you can bottom the suspension out over a bump or pothole.
Warning: those HF frames really don't have much suspension travel, and if you build heavy and do the axel flip, you run a pretty good chance of bottoming the axle onto the frame.
Sorry, I just re-read your question. You asked "what time is it" and I've told you how to build a clock. . . . I do that. Watch out for clearance problems with bigger tires and rims.
