Probably a typical D44 parts changeover and some custom 8 lug shafts for the 9" with some redrill drums or drums off of something 8 lug with same size drums.Front is Straight Axle Dana 44 and rear is 9" Ford all converted to 8 Lug.
No axle company claims to be able to make 8 lug 9" shafts. Foote says they might be able to a few yrs ago, but they were going to be $500+ per side.Probably a typical D44 parts changeover and some custom 8 lug shafts for the 9" with some redrill drums or drums off of something 8 lug with same size drums.
Would need custom shafts or adapters. Flanges aren't big enough on 9" blanks for 8 lug.Ad says the Axles were converted to 8 lug... So probably not adapters, I'd guess they drilled a different bolt pattern axle to 8x6.5.... An untrussed 44 with 39's? I wouldn't expect that too last....
By the looks of it I don't believe its ever even seen a dirt road
