I havn't worked on any of the newer vans, but I had both a mid 80's Dodge 1/2 ton van and a mid 80's Chevy 1/2 ton van. Both of them were much easier to work on after taking off the "dog house" inside - the center console came out by unbolting two bottom bolts and then two top latches on the inside of the truck and then removing the whole "dog house". Then I just sat in the drivers / passengers seat and changed the plugs / carburator / plug wires / distributer, etc.... MUCH easier.
Hope this helps.
