Hybrid Autolite Distributor Can of Worms?

[PT81PlymouthPickup]

In my quest to figure out engine stumbling at mid range rpm, I discovered my distributor bushings and shaft are worn out. Not positive it will be the cure, but definitely needs to be repaired. Excessive lateral play at .013" and also the governor weight pivot pins were shot to the point that the weights are beginning to dig into and catch on the base plate which is mounted to the shaft. Here's my dilemma; During this exercise I've also discovered the distributor in my truck (IGS-4003-1) was not the correct one for my 39PT81. It's listed for earlier Plymouth cars. So, I've procured a IGS-4103 which is what should be in the truck. Unfortunately, it's in worse shape. I also had laying around a later IAT-4011 which has a good shaft and looks like it will work in the earlier distributors. It has a different, but more robust governor setup. (larger pins). I may be asking for trouble by mixing things up, but sure looks like it may work? Opinions or advise would be welcomed. 1st image is IGS-4003, 2nd is IGS-4103, and last is IAT-4011. Notice the difference in springs. The IGS-4103 has springs of different sizes which concur with my dodge master parts catalog?

If the IAT 4011 is in good condition, why not just clean up that one and use it in your truck?

Thanks Merle!  It could be used, but the housing and mounting flange is different which locates the vacuum advance and oil cup in a funky position. I would have to remake the vacuum line too and although it probably would work just doesn't look right. Did I mention I'm too fussy for my own good! Lols!

Thanks JB! Sending out for a rebuild would be last resort for me, but it's good to know that there are some outfits that do quality work. Very, very hard to find these days.
