Why do you need a kit? Just buy a mount, a hub, and a wheel/tire. It's really not hard to find this stuff.
I know I can cobble it together, but would like the piece of mind knowing that all the pieces will work together ie. ( back spacing on the hub,wire harness that is not just a donor harness, also I want rear disc so I was hoping to have the caliper and hanger together so I know the offsets are right for rear shock clearance). Actually last night I got set up with two solid suppliers,that have great fill rates and good products with quick turn around times. I'm in Florida and can now get long cases in 1 ship day and have a list of all products we will be offering with them... flat slides, pro intakes, yoshimura pipes, wire harness with 11 pole already in place,calipers ,rotors, tires, bars,custom seat pans and custom seats. Keep in mind this is going to ba available soon and there is going to be plenty of it. I have been a pm in multi line dealer for 15 years and fully understand the concept of supply and demand.
Golden rule 1
You don't ever run out of something that is your best seller, you have 90 day supply.
If you sell 1, order 2, you sell 2, get 4 etc.
