I think GDemon used the car manifolds, but you have to clearance the frame rail on the passenger side with a cutout. From what I head the Jeep manifolds fit with no modifications, but I've not seen it in person. That's the route that some magazine took with the swap (I think Hot Rod maybe). I think the truck ones point right at the firewall, so while they may fit the bay okay I think it's hard to get pipes on them. I ended up going with TTI headers and while tight, everything fits okay. I was planning to use the LX car manifolds that came with my engine, but didn't want to cut up my frame.
