sellin it to put a tuffy console in? I put my tuffy console right over top of my rear heater. Fit like a glove! (my truck's a 88 HJ61 - it might be a bit different then yours, but it sure looks the same.) anyway, hope you sell er!
Might be different on a 60 series. I suppose I coulda hacked the Tuffy, but I'll take the space inside it and a clean look over having the heater in there. I rarely have anybody in the back, and to be honest the front heater is pretty toasty enough for the whole SWB interior.
