Difference between 95 5.9 and 02 5.9

Salvage yards told me earlier blocks would not work in my 2002 B1500 because of motor mount differences. I found a 97 model from a truck to build and it fit fine.

The 93 model year trucks should have been the first use of the 5.9 magnum engine. The 5.2 was used in the 92 model year trucks. I have a 1993 D250 with 5.9 Magnum. This truck has the bosses on the engine block used in 94 and later trucks for the engine mounts but the bosses are not drilled and tapped. So they are basically correct in that a 93 model year 5.9 Magnum will not bolt into the newer trucks, and I would suspect the 92 and maybe 93 5.2 blocks could be the same way. Not sure when they started drilling them, but all trucks 94 and later using a Magnum engine have the newer engine mounts, so it should have the blocks drilled.
I forget the what the B-van engine mounts were set up like. Durangos used the truck style bosses I think, with different mounts.
