Rear suspension setups

Hey guys,
I have the SS springs in the factory location on my 70 Duster with an 8 3/4. First of all, I hate how high the car sits, and I hate how the leaf springs sit in the middle of the wheel well keeping me from running wider tires.
I get crazy amounts of wheel hop on take off and because of how high the rear end sits, my pinion snubber is useless.
I’ve been looking at 3,4, and 6 link conversion kits but they’re all pretty pricey and I feel like a well tuned leaf spring setup will work just as well.
I’m thinking of going with a USCT spring relocation kit and some Hotchkis 1 inch drop springs and sway bar. That way I can fit some big ol meats out back, lower the car, and have a useful pinion snubber.
I like drag racing but there’s only a lame 1/8 track near me, and I like road racing/autoX more anyway.
So I’m thinking of setting it up to be more of a road race car than a drag car.

Anyone have any experience with the USCT relocation kit? Or some drop springs? Or just an opinion on any of this?

Thanks!

Almost as much ground clearance as my truck.
