Bolted direct to tranny or with a short driveshaft connecting the two? I always associate Napco with brand X trucks. Last year before I was involved much with this site I passed up a '52 F3 with a Coleman conversion. That thing was nice too. I might just pick up the transfer case from my buddie's '58 3/4 ton Apache, specially now that I know Napco did fords as well. I can check the numbers on it next weekend easy since it is already out of the truck. Please post up some progress pictures as you go along. 'Before' pictures are always good!
