Perhaps a function of G70 RPO. Order leafs, get a D60. I've had this in one C20 also (with original 350 also). Since GMCs came with leafs standard, believe D60 more common in a GMC C2500.
To Dieselwrencher's point, I think big block with an automatic automatically drove a buyer to a 3.54 ratio - and the only way to get that was via D60.
