My short side is 20-5/16” custom length and the wms is 65”. There really isn’t a point in running off the shelf shafts because you will have to rework the polished area for the seal, unless you already have some badass shafts laying around like Blase.
These are still available at Dutchman last I checked, add $58 for shipping and you have a set of inner 4340 shafts at pretty much whatever length you want without having to compromise your pinion offset or wms.
Also no way I would consider using those thick ass tubes on any junkyard built 9. The ones I used from a Dana 50/60 were both .350” and I would have liked to have gone thinner like .250” that is used on a lot of 14 bolts. I’m pretty sure most or all the van axle 14 bolt ff housings are .250” wall. I’m not sure if you will have enough tube for a long side without splicing though, which is another reason to run a longer short side shaft/less pinion offset on your front axle build.
That’s a 14 bolt FF next to a Dana 50 front or e350 rear tube, both 3.5” OD. If I had enough of the thinner tube I would have used that instead of the thicker tube from the danas that I ended up using because I had it already.
