I realize that it says 1976 and back application, however the same part was used in 19777 1978 1979 by the picture. If the part was the same, the bearing should be the same, unless now we are disputing which typo was most significant.
7a185 to 7c431 bearing. 1977-1979 diagram your diagram show that to be 1977-1979 auto trans. 7a185 being bell crank and and 7c431 being bracket on bellhousing. I rest my case.

You cannot go by parts catalog pics to ID what parts fit, because only basic part numbers are shown. Ford has used the same basic part numbers for decades.
Only when the prefix and suffix are added from the text to the basic part number, do you get a complete part number.
Example: B4A-7A185-A .. Bellcrank = 1954 Ford Passenger Car with 239 Y block.
You can argue till you are blue in the face, but the facts are, the EOSZ-7C327-A/B bushing is ONLY listed for 1973/76 F100 4WD and that's it!
The top of this parts list reads "1973/79 truck series 100/500" but only goes to '77 where are the 78-79 part #'s?
not a single part listed for '78-'79 model years
Awe shucks, you got me Bill, & I should have known that but thank you sir for the schooling. Also, I'm now the proud owner of the 1973/79 truck master parts & accessories catalog!....believe I can read it & willing to be tested for your approval too!
unless I'm mistaken, the bell crank assembly is made up of 2 different sub assemblies...
D7TZ 7A185-A which I know was said to be obsolete.
& D7TZ 7431-A for the full time 4x4.
or D7TZ 7431-B for the part time 4x4.
Also, I found this interesting...
I do realize this diagram is for the '73-'76 F100/F150 4x4 & the '77 F150/F250 4x4's, but it's showing a lot of the same numbers.
& lastly...
Group#7341 =D5AZ 7341-C...this # has eluded the discussion & it is for model years '73/ edit: I just seen in post #10 that EOSZ7341B replaced D5AZ 7341-C
I have some grommets/bearings on the way. I say they mic out and are probably the same ones. I will install and follow up. Mine are pretty worn, so the bushing kit would be an improvement. Mine probably takes that same part and If it fits, numbers approval or not, I bet there will be a lot of 79s get that part. It is like the old transfer case mounts that are obsolete, take a newer mount, cut it shorter and it was the exact same bushing. just longer for newer trucks.
Power to ya F-250 WARHORSE & Cougar2, I hope this gets sorted out. I have yet to find these parts to post pics for reference...got 1 more place to check...maybe Cougar2 will get his posted.
good luck!

I will be posting pictures of the parts I took off , disassembly and rebuild later today. I am rebuilding the shaft ends and with what parts I have found "bushings at other locations" not related to our trucks. Im making the fit the bushings that are available from other sources/vehicles.
When my bushings arrive, I will measure and install. If they fit we have the start of a solution. I built a spring loaded taper fit sleeve/wear shaft apparatus for mine a few years back. Worked well so far and cheap, but I am an oem guy if I can be.
Ok, so I now have the modifications finished and the result is quite nice and a good solid feeling in the shifter. There are lots of pictures so I will try to post all of them and what I did.
You will see the od shaped bushing in the bellcrank and I also feel this was not a replaceable part. . You can see in the first picture that there is a metal cap over the end of the shaft to lock it together.
You can see the ware I had in the shaft, so I cut it off and drilled and tapped for a new shaft. I would have built a whole new unit, but lack of time. So this is a temporary fix for me. I also used a self oiling brass bushing, but could have used a plastic one I found from an old stock of Chrysler parts in a parts tray from Car Quest. I would have had to drill a much larger hole in the bracket to install it, so I opted out.
where are the 78-79 part #'s?
