Chevy van with 6.5TD wanted

[75-K5]

I'm looking for a 6.5TD out of a Chevy Van. I'd prefer to buy the whole van so I'll have every single necessary part. It would help if the van itself is in crappy condition though so it would be cheaper . I'm wanting to swap a 6.5 into my '78 motor home on a G30 chassis. Thanks.
