Thanks guys! So I just need to find a shaft from a 208/241 truck….I’m headed to spring Carlisle this weekend and I know a guy that deals in CUCV parts so I’ll see what he has
My 84 crossmember was flat and my 86 is a W. Both have 208’s.The front drive shaft got longer when the 208 came into service. I believe almost 3" longer.
Here's the 208 with the steel skid plate from a cucv. There was also an aluminum version. My 84 has the flat crossmember, I'm pretty sure in 85 they had the w shaped crossmember.View attachment 409921View attachment 409922
I’m swapping in a front Dana 60, which is why I originally thought my 203 shaft would work, I thought maybe the 60 being longer would take up the difference but 3” is a good bitA CUCV driveshaft may actually be too short, as the Dana 60 is much bigger than the GM 10 bolt used in 1/2 and 3/4 tons.

Definitely not out of the realm, but that definitely requires swapping in the 208 as I don’t think driving down the road with a square shaft would be pleasurableWhy not build a square front shaft? I did that on my wheeling rig and I like it.... uber amounts of slip and a lot beefier. I got a weld on yoke for the axle side and cut the CV off a stock front shaft and welded that on.
I bet the 205 shaft is the one that's shorter. Goes to show just when you think you've seen everything on these trucks there's more information lolWell the 208 is in, got the linkage all installed tonight and took it for a ride…I don’t dislike a 203, but I like this 208 a whole lot better. No more bucking on tight turns, the low range is wayyyy better and I think the truck feels less “draggy” on the road. I learned a couple things that may be useful to others….the 400/203 front shaft is the same length as a 400/208 and the strut rod from the bellhousing to the transfer case is also exactly the same between the two (I had three others to try if it wasn’t)….hoping to swap axles this weekend…

…only issue ai have now is that the CV on the front shaft ever so slightly rubs the crossmember…which I can’t figure out because everything is basically as a factory 84 truck would be set up? I suppose I could clock the t case up…I’ll get some pictures up here shortlyNo I didn’t yetClearance the cross member, did you grind the stops out of the front cv?
