Thanks for that, have been tossing up what to do all day.
Have been looking at a Lokka for the front, and it already has a factory locker in the rear (I'm guessing detroit). Dual locked for under $600 sounds good to me.
Springs I can get cheap, shocks I can build at work to whatever lengths I want. Am not set on any height in particular, was more looking for clearance to run larger tyres. Ideally I'd like to get 32x10.5R15's under the guards, and am not afraid to do a little trimming if need be.
SYE and double-cardan rear shaft have been on the cards as more of a safeguard than anything else, but can be put on the back-burner if need be. Will be doing a hack-n-tap SYE as it's the cheapest and easiest option.
Rear-quarter chop with custom bar is also going to happen, I'll weld it up myself using pre-bent sections for simplicity during the build. The more clearance, the better.
