Thanks boys. Didnt do much this weekend, but did manage to clean the shop, and get the rear driveshaft mocked up. Found a random spicer shaft at the junkyard with a 1350 CV and flanges.
My Sterling 10.25 is an early one (1980's) and hence has what is termed a 'short' pinion. The housings and everything are identical for all the Sterlings, and you can throw 10.5 gears from a newer Super Duty in them, as well as running the long pinion gear set. When I order my gears, I will get a long pinion set. The later (1990's) Sterling 10.25 had what are termed 'long' pinions. The long vs short is referring to the splines on the end of the pinion for the yoke/flange to attach to. My Sterling had a short pinion with a yoke, and I hate yokes. I got a flange from a 2005 Sterling 10.5, here they are side by side.
Short yoke
Here you can see, there is almost a 1/2" more of spline in the long version flange.
Here is the shaft, I cut the slip section apart and cleaned it up, and trimmed to approximate length
and tacked together for mock up
And under the truck. I need to rotate my pinion down just a hair (havent welded perches on yet, was waiting to mock up DS)
Because Im running a CV and due to the extra length of the M5OD-R2/BW 1356, it gives me lots of DS ground clearance.
The slip section of this shaft is pooched, however the flanges and CV are in awesome shape (would just change out for new u joints). Ive been toying with the idea of just ordering a new slip, getting everything to the right length, then having the machine shop weld it up as true as possible/balance it...this should save quite a bit of $$ rather than having a whole new shaft made .
And a pic of the whole rig on its wheels for $hits and giggles, its got a mean forward rake, when its done it will be a couple hundred pounds heavier in the rear and will level it out.
