but the OP want the 60 series look and body ..?
80 series frame is much heavier and beefy. If you plan to run a ton of hp it might be needed.
Three shops I know of have recently grafted 80 suspension only onto the 60 frame. Reducing the amount of time/labor/parts needed to pretty much execute the same thing.
I recommend talking to would be @torfab (Torfab) and @ddelong6767 (Wellsorted)
They both are headed to CruiseMoab (this week?)and are running 60/62’s with these swaps done. I’m hoping they have video of these rigs on the trails (common Adam & Doug!)
I’m personally have added a Leaf spring 80 series axle out back and would interested in running a coil spring 80 axle in the front (a la 70 series style) check out @bdyer12’s sick build on his 87 of this.
Word is it handles very well.
