6.1 Swap into a 68 Dart

Hello
I'm swapping in a 6.1 into my 68 dart, I have read Real Wings restoration and it's very impressive. Great job.
My 6.1 is out of a 08 Jeep and I do have the stock exhaust manifolds that I would like to use, not sure on the steering column clearance past the manifolds to the steering box?. This will be a cruiser if all works out.
I want to keep the EFI setup that it came with and put a 904 trans behind it (body work is done and I don't want to cut up the floor for a overdrive unit), so my plan was to go with Bouchillon's computer and harnesses with their Gen 3 Hemi kickdown system. Has anyone used it and can comment. I know there are other systems but I would like to use as much of what came with it as I can.
It sounds like the Napa 4N6987 is the starter to use.
I was going with the stock K frame member out of a 73 Dart, I have read that a few guys have moved motor mounts around and are able to keep the AC and power steering, not sure if this is a route to go or not?, my AC is tucked under the the driver side of the engine by the K member.
If I can't go power steering is there a block off plate for the power steering pump?

Thanks
