Allison to Passenger Side Drop T Case

I'm building a 1971 International travelall with a lb7 and Allison transmission. I'm running a dana 60 king pin front axle that is passenger side drive. I'm looking for a Transfer case that i can adapt. It seems the np261/np263 are the only t case that bolt right up to an Allison. Id like to run a manual shift NP271 and flip it but not sure on adapting.

Thanks

Your best way to go in my opinion would be to us a 2wd Allison with a divorced transfer case, that way the Allison gets its third speed sensor pick up from the tail shaft and you can use whatever case you want.

Look for an 01-10 C4500/C5500 they came with a 2wd Allison, a short jackshaft, and a divorced NP273 with the passenger side drop. You could easily tack weld a shift lever on there and make it manual shift. That way you'd get the trans, jackshaft, t-case, tcase mounting, etc all at once.

There is a company that makes a 205 adapter for the Allison
