I like the third truck pic posted by xaman, it holds the rust look while keeping all originality, just chopping and lowering wont do the job, you will need a v8 and front disks for it i.e. changing front clip changed, need air ride etc. what i mean that it will be a radical job, so its better to store it like the 3rd truck for a while , i think samad have frontclip of a v8 which he got for putting v8 in the truck, you got the V8 from it , so get the front clip rebuilt the V8 chop the roof around 2-3 inches , put small shocks , cut few leafspring ....
