273 engine swap into a Jeep CJ5

Thanks everyone for the great advise! I am new to the Jeep CJ5 arena. The engine runs great right now ... it was an Arizona Jeep and virtually no rust on it so I'm going to lift the cab off and freshen up the paint and while it's off I'm going to clean all the frame and pretty up the engine... I'm kind of leaning towards the Dual carb... thanks again for all of your help... it needs a few things like tail light lenses and the pull knobs for the heating system are there but they come off when you pull them... Any suggestions on places to acquire Parts like this... also fuel gauge not active.

Thx again!
