anyone,anyone??
I am assuming it was dependent on year just like the Chevy's because I know there are both styles available. My friends '78 Ford with the factory front D60 had a neckdown shaft on one side, and a non-necked down on the other. We assume that the non-neckdown shaft was a replacement at one time but don't know for sure (the truck had a 460/C6 swapped into it on custom motor mounts, etc...so definitely not an original truck, but it did come from the factory with the front D60).
