yeah, I've already given eriks military surplus far too much of my money :laugh2:
agreed, no way am I installing a flame heater in the cab. The seats have a couple inches of padding on them (well the new ones I bought from TNJMurray do anyways) and won't stay all that warm, and the cabin is very drafty from all the leaks around the softtop, so I'll probably go with the heater core idea. Just not sure how big a heater core I will need... like I said, might end up using a whole XJ radiator or going to the junkyard for a smaller one.
