Please help to select the right stuff, Distributor, wires...

I have had people call me to see if I could do something about it, just a few. I do like that setup, coil in the cap same as a gm module system, All you need to do is run a hot wire 12v to it. Probably guys doing a sb into a slant k member.
It's very very tight at the fire wall on a lot of our a-bodies in there - even with the v-8 k-frame etc.
I would not gamble on distributor height and a wider and taller cap when mail ordering from out of country.

@Achill take some photos and make some measurements of how much room is available.

Or make a silouette out of cardboard.

Regarding engine size: American Motors Corporation (AMC) made a very different v-8 engine that had displacement of 360 cubic inches.
Those AMC engines continued to be installed in some Jeeps at least through 1991, even though Chrysler had purchased Jeep in 1987.
Those AMC v-8 engines have the distributor in the front of the engine, and engage with a gear.
The Chrysler distributors engage into a slot.

Do you still have the distributor from when the engine was in the Jeep?
