Redline supply all the parts in a kit, the electric choke version being K551-38 buit there is a manual choke kit as well, number escapes me.
For the kit Quadrateceh is about $390 plus shipping, eBay is about $300 plus shipping. You can find cheaper but you must buy Genuine Weber with Made in Spain and the logo cast into the metal, not a rebadged Solex from Weber USA.
However they supply the chrome rectangular filter which filters air and not much else. If you have the original TAC system on your CJ it is worth retaining it and there is an adapter to keep the original air filter which is IMHO much better. If you have a snorkel there is another adapter you can buy which fits to the top and allows a fender mounted filter system and snorkel set up.
Make sure you have the manifold adapter and accelerator linkage kit if you find just a carb.
When you get it check the bolt lengths for the manifold adapter, they are often too short to go through the adapter and the phenolic spacer the BBD had. The spacer helps with heat transfer so worth retaining under the adapter.
