Rusty, as the saying goes, "your mileage may vary"; not sure what nose weight you have so I can't compare, but I have a SB, mostly stock K with 6-cyl bars, its original setup from its SS/IA days. 2 batteries in trunk + the ballast.

I can't recall what wheelie bars we used, maybe Morrison's kit; we narrowed them and they mount to the rear axle. They're spring-loaded so they don't unload the rear axle/tires. Had to narrow the stock fuel tank on the right side for the right wheelie bar because my Dana's fairly narrow (3" spring relocation, 13x31s). One thing leads to another, you know.

Easy enough to fab a block-off from light/thin sheet aluminum, or leave the area as-is without the controls.
