combination UV joints
Does anyone know the part # for the combination UV joint? I called Napa and gave them the specs of the UV joint I am looking for but the parts guy I am assuming was drooling on the phone. I need one that allows a '68 F-250 rear shaft, UV width 3.620", to mate with a '66 F-100 9 inch pinnion yoke, accepts UV widths of 3.215" I have the front part of the '68 shaft in the truck with the rear of the '66. The owner wants the same diameter shafts so it "looks" stock. Both UV joints have the same diameter bearing caps but different widths. Thanks for any input.

Mark, try calling it a conversion joint, that might help. Usually the newbies don't understand a lot of this, so the next step might be to take the driveshafts down to the parts store.
Take the '66 driveshaft (that used to mate to the '66 pinion yoke) and the '68 driveshaft that has the yoke you want to mate it to.
The additional issue is not just in the cap diameter, but also in the trunnion length - and having them in the machinist's hands will allow him to measure and determine exactly which one you need.
That is exactly what I did, and the fuzz faced kid quickly called for the grizzled guy out back to get the answer when I showed up at the counter.
Not to rag too hard on the fuzz faced kid, as we were all there once, but today's kids don't seem to know the words "I don't know but I'll find someone who does."

Back when we still used books, the combo joints were shown in the back of the catalog with drawings and sizes that made picking the right one pretty easy. Now that counter help relies on a computer screen and "What kind of car do you have?" it isn't as simple to get what you need.
I concur, your best solution may be a driveshaft specialist.

Well the good thing is that in the meantime I am able to run the original back shaft until I get the right UV joint installed on the '68 shaft. Right now I am chasing a charging system gremlin so the driveshaft is taking the back seat. Damn thing is evading my multimeter and wiring harness repairs. The PO did a heck of a job swapping wires and not keeping the colors the same.
Bill the problem isn't cap diameters, they are the same. It's the width, outer cap to outer cap length, difference of driveshaft and UV joints that is causing some headaches with the parts guy I spoke to. One is built for a Dana 60 and the other is for a 9 inch.

Mark to get a "conversion U joint" you will need the end to end measurement both directions and the cap dia both directions also will need to know if they are inside clip (big C clip) or outside clip(looks like this @ thingy.

All four: 1 1/16" O.D.
Length/width less caps: 3" X 3 5/8"
This is the only one Ford supplied.
I've seen others that are 1280/1310 & 1330/1350 but they're not Ford parts.
They are Spicer type.
Outside locks = Spicer type
