You'll need an adapter plate to bolt to your intake. I used a Mister Gasket from Advance Auto. Part No. 1937. $20 or so.
A way to adapt your air cleaner, the Jeeps is 2 5/8" (?) and the MC 2100 is a 5 1/2" (?). I just bought a 9" round air cleaner assembly and made life easy on myself. Another $20 or so at Advance.
A new throttle cable. One from a CJ with a 304 will snap right in to your firewall, and be the exact length. Some make a bracket at the carb to hold the cable, some don't. I didn't, and see no problems with it. Another $20 or so at advance.

I hope u got it from a good source on there. When I got mine it was the wrong size and way out of adjustment and jetting was way off even if it was the right size. And the guy wouldn't repsond to my e-mails. After I got one from a junk yard and rebuilt it I love mine. Good luck.

Just ordered one off ebay for my 258 inline. Hope it works any advice?
Make sure you use the correct adapter plate and gaskets. I would use a very thin amount of RTV to ensure you get an air-tight seal between the manifold and adapter plate. You don't want any vacuum leaks.
Know how you'll be handling the throttle linkage, as there are a couple of ways to do it (keep the original down pull, or modify to use back pull).
Make sure you have a new fuel filter and it's oriented correctly with the vent line on top.

I think most people fabricate their own rigs, though. My MC2100 is set up for down-pull and has a "T" bracket (mending plate, used for woodworking) screwed to the original throttle arm, and there's a throttle linkage ball screwed to the T plate. The original Jeep throttle linkage pops right onto that ball. I think I ended up cutting the linkage and rotating one end 180* and welding it back together. It seemed to fit better and work more smoothly in that orientation.
