I don't know about that , because we had 3 T950.s all 1964s bought new one 534 5x4
and two with Cummings 5x4. I usually drove a diesel and the gas job will blow the doors
of the other two and that inludes Macks Petes etc. You didnt even need the aux trans
they started talking around 3000 rpms tough on gas maybe 3mpg, never broke never
failed, so for $0.30 a gal nobody cared. sam
