NO.
'74 to '77 CJ's ('75 to '77 FSJ's) used the Prestolite distributor and ignition module.
There are currently no upgrades for this system since it was discontinued and abandoned after AMC stopped using it.
--------------------------------
*IF* You have an AMC I-6 engine, you can switch over to a HEI distributor from a Chevy 250 CID I-6 engine,
You will have to change the distributor gear and some other things, but a Junk Yard or Remanufactured HEI distributor will work in your AMC I-6 Engines.
(I wouldn't buy aftermarket HEI distributors right now, too may problems with parts eating up engines and falling apart)
OR,
You can switch over to the distributor from a '79 CJ-7 with 258 CID engine, do the cap, rotor, plug wire upgrade and wire up your own choice of modules.
(It's easier than you think!)
If you have a V-8, there is no facotry GM HEI that will work for you, and the aftermarket HEI distributors haven't had a very good track record lately...
(Bad import parts are causing REAL problems)
That only leaves the Jeep/Motorcraft distirbutor used from '78 to '90 in AMC V-8 engines as a reliable, cheap replacment.
Again, you have 2 or 3 module options you can easily use with the Jeep/Motorcraft distributor, and after a Cap, Rotor, Plug Wire upgrade the factory Jeep/Motorcraft distributor will run with any of the 'Factory Style' aftermakret distributors without the cost or problems they bring.
