if the van you have has the gm cummins adaptor it will not bolt up to your np435 ford bellhousing but you could just take it apart, gm cummins adaptor, flywheel and so on and ether sell it and buy what you need or just trade im sure someone on here will trade your gm stuff for there ford stuff try looking in the classified section. steve

What year is this rig? Ive got my eyes on doing a conversion for a friend in a 55 F-100. Looks easy smeasy. I like to look at how others go about it AND if he can see that its possible instead of hearing me yack about it, that helps. Post pics if you get anything going.

how old is your f banger ? i put one in a '77 2wd relatively easy. there is a thread in the buildups section. have a good look at your adaptor. it may have the ford setup on the back already.
