I didn't choose it, but on my 1939 F60, the shop used a front clip from a RWD 1988 Cutlass. The width seems correct and there is plenty of clearance at fender wells. After it was all together, I measured the wheel base and the front wheels were 1.5 inches back from the original position (wheelbase 113.5 inches).
I think the shop might have done this because the power steering pump just barely clears the front sheet metal. I would have rather had a small hump put into the front sheet metal below the bumper in order to keep the wheelbase.
