It should be fine, they may want to read the bowl tag to be sure they have the right kit. Short of that you would need to know exactly what vehicle it came from. Also these kits almost always come with a 7.5HG. power valve. Mine required an 8.5HG PV. On you tube I found the Holley Power valve video. It explains how to figure out which one you will need. MC2100 uses a Holley PV btw.Take CYJKrawlers advice, it's good advice.
 
I would look for vacume leaks. get a friend to put his hand over the carb at idle and see he can get it to stay running. My wouldn't idle for shit and we ended up fixing about 15 vacume leaks in about 30 min.
 
check the vac hse goin to power brake booste. my old 87 wrangler cut off when stopping even after mc2100 swap, nutter bypass and distribtor cap swap. my vac hose going to booster was leaking when brakes were mashed.
 
Everything works great on the new mc2100 carb so far and the nutter bypass works also. Thanks to all you guys who helped me out. Anyone who reads this thread or has similar problems definetly go with the mc2100 carb with the 1.08v only and youll be fine.:driver:

Good deal, now you need to do the ignition upgrade to make it even better!:beer:
 
my jeep did the same because of a shit ton of vacume leaks....I would start by checking that
