Am I crazy
 

I have a 1988 E-150 conversion van that has 302 and auto tranny. The van is in really good shape. I have the chance to buy a 1988 f-250 4x4 diesel rolling chassis. (no body). I am thinking with a liitle work I could have a 4x4 diesel van for a little work. What kind of problems am I going to encounter. Will the truck motor mounts work,will the diesel fit in the engine bay, can I swap front coil springs. This would just be something a little unique. I could also use the 302 in my 1950 f-2. What are your opinions and comments. Thanks

You're certainly no more crazy than the rest of us. Just not too sure about the "a little work" part.

Just remember the van frame is wider than the trucks.

This dude did it to his, plenty of good info there:
