D100 Pickup question for you:

I have a similar truck but newer, an 82 D150 with a slant. The trans is the 833OD which works OK around town but I've already figured out if I'm hauling any weight or pulling my trailer, first gear is too steep to get going very well. If you're using yours as a cruiser, a different trans might be in order. If you're using it as a truck the granny gear is a good thing.
