I have a 91' xj that took two roll's with no roll bar.

I found an 88' in the junkyard with no collision damage for $400 pretty much stripped.Would this be a big mess and headache or worthwhile considering the money saved?I have already put a new motor in,fixed yoke,6" lift,roll on bedliner on floor and my first paint job.All the work done myself,I have enough paint left for another vehicle and will put a roll cage in.I feel confident I can do it but the dash has to be swapped and that is the only part on the vehicle I haven't removed.Any help is greatly appreciated,thank's!
