good picks of some extended units with the drop accounted for at the C end.

The pinion angle and amount of lift is most likely why the builder left this steering angle in less than perfect condition. If you don't change the RA mounts by pushing them rearward the axle gets pushed forward. By the pic I am guessing those are not terribly longer than stock.

here is a good pic of a factory arm location. How is it related to yours compared to the body mount? Original Fords were actually quite long. I almost wander if the C portion was rotated some in fabrication compounding the problem you are facing.

I'll measure my arms tonight but I caint move the mounts any more rearward bc of the mounts for the 4 link rear. I'm pretty sure these are aftermarket RA and I know for sure they aren't stock

How do you figure the driveshaft is limiting travel?
 
Maybe not Lol? Only has a 1/4 inch of slip left until it bottoms. And that is with the truck just sitting there. I was thinking maybe when suspension compresses it's bottoming out?
 
You sure it's that close to bottoming out? It kinda looks like it's half way. I can see a line where the seal wiped about 1.5" higher than where it is now....about half way through what is left of the shaft.

If it IS that close to bottoming out then I'd definitely get it shortened. It wouldn't limit your travel though...it'd either bust a u joint, bust the transfer case adapter, or break the transfer case :D

X2. Unless it's rusted so bad inside that it's binding up, outs nitty limiting travel. It will pull apart or break something before stopping flex.

I disagree somewhat.....depending on use or abuse a bottomed driveshaft will limit travel. Not everybody makes a point to slam into everything while wheeling or have a full throttle assault approach. If it is truly the bottoming factor over time failure Will occur somewhere. Failure may not be as instant as you make it sound. Old cast iron cases and even trans adapters are fairly strong. Every build past mild it is a good idea to cycle everything less the drive shafts to get proper engagement in all points of travel.
 
Are we all looking at the same driveshaft pictures or is there a different copy somewhere?

Bottoming I agree. I was thinking more about extension. The driveshaft looks to have enough slip in out to not be the thing limiting his flex, though.
