having trouble with figuring trim level and carb help
my 1984 fb trim level is hard to figure ok its a 12a 4 wheel disk pw ps sunroof power mirrors lsd diff rear wiper and came with air dont no if it matters also have the stock carb but its screwed the best replacment besides the nikki would be ??? for ease of repair and cost.
welcome to the board. 
the best i can do from what you described is you either have a heavily optioned GS or a GSL. i think the GSL is the likely scenario though.
for a stock or even mildly ported engine, the best carbie to replace a Nikki is ... a Nikki. i know many around here that share that opinion with me. that said, the best aftermarket replacement is going to whatever type of carbie you (or whomever will be working on the car/engine) is familiar with.
aftermarket pretty much breaks down to Holley and it's clones/peers vs. Weber and it's clones/peers.
RB still offers Holleys brand new. they do most of the work for you in order to get them to play nice with a rotary engine. it's not perfect, but if you don't know carbs or Holleys, in particular, it's closer than you'll ever get starting with an off-the-shelf Holley. that's only reason i chose to mention RB because Holleys (in my experience) are more involved/complicated to rebuild, tune, etc. than Weber and Weber-type carbies.
people have also used Edelbrocks and Demons on Holley manifolds with success, but again, you'll pretty much be on your own getting them to work.
Webers are still available new as well. as i mentioned earlier, they are a bit easier to tune and in some cases, the carbie can even stay on the engine. they are typically more expensive though.
for Weber-type carbs, you have Dell'Orto and Mikuni, to my knowledge they are not available new any more. so you can look for them used, if you want. i can't speak on support for Mikuni, but Dell'Orto still has lukewarn support out there in terms of available parts.
my advice is if you haven't had the car very long, do yourself a favor and keep a Nikki on it. if you're not familiar with carbs, keep a Nikki on it. unless your plans include radical engine work on a quasi-race car level (in which case, i would say go fuel injection anyway), keep the Nikki.
