No Limit 63-72 Rear Shock Kit

[GBJ]

My setup is just like BugzC10 so if anyone comes up with a length it would be appreciated. Also I was wondering if anyone has tried to keep the stock shocks as well as adding the kit? Either by flattening the OEM bottom mount and putting new one on top or putting OEM mount on top of new one? Not sure how much extra anti wheel hop it would help or not. I have a Vortec 5.3 with Texas Speed 2.02 / 1.575 heads, 228/228 600/600 LSA cam and 42 lb injectors so she runs pretty strong. Running Nitto Extreme RT tires, 20's roughly 11" wide. If your looking for a good tire these surprised me, they came on the truck and are a drag radial/track combo. Being my first set of low profile tires I expected them to be rock hard but they hook up pretty damn good.
Thanks,
