Will this distributor work with upgrade

I have a 77 CJ with the 258. I'm trying to get rid of the prestolite ignition and upgrade to motorcraft ignition. I had this distributor given to me and wondering if it will work for my project. I looked up the numbers that are on the tag but haven't had any luck. Would this be a direct drop in?

If it's out of another AMC inline six cylinder it will work. That's a Duraspark distributor that AMC started using in '78.

I want to emphasize that although the distributor is Ford, the gear is different. I've got a '77 and I too got rid of my Prestolite distributor and ignition. I've got to admit I've never looked back since.

You MAY want to consider an MSD ignition instead. The installation is incredibly easy and I can't believe how much better my Jeep runs. I've got a manual choke on my carburetor tht's broken, but I've got to confess that the spark is so hot I haven't bothered to repair it. (I live in NORTHERN Arizona where is does indeed snow and get cold) Sure I play with the accelerator a bit until it's warm, but with the MSD it starts right up.

And you're already on your way with a new dizzy anyway...
I'd rather be lost on the trails than found at home!

SUPPOSEDLY for a '79 4.2..
I'm no expert on I6 but it looks like it OUGHT TO work.
If it's good TO you, it's gotta be good FOR you....
