When I installed my Howell conversion, I used my original air cleaner.

I found a plastic adapter that was from an aftermarket air cleaner to fit a Mopar. That gave me enough height to clear the linkage, and the air cleaner looks like it did when on the carb. I used the same flexible air hose from the core support as well. I did this primarily to prevent any water from splashing up into the air intake.
Another thing that does not come with the kit is an indicator light. This is also known as the check-engine light. You can pick one up at NAPA or Autozone, must be 12 volt. You will need this light if it throws a code.
Everything else is included in the kit, and the instruction sheet is detailed enough for any shade tree mechanic to understand. They also have a tech line phone number to call in case you get stuck.
Here's a tip: when you need to cut wires, clean them first with a little lacquer thinner on a rag to be sure you're cutting the correct color wires.
