I forgot about the ps pump.
if you use the stock one out of a truck, it goes wider and higher. puts the cap right under the battery tray.

I happened to get lucky and a pick your part was doing an all you can carry for 25 bucks when I first started the swap.
I did not know vans were different, but pulled the whole front end off the mag motor in that van, a dakota, and a bunch of starters.

anyway. turns out the van one tucks it in closer to the engine and drops it down.

so it just barely clears the battery tray.

you do need a weird belt too. it didn't match the van belt. but is a common one the parts stores carry.
