unless the 1 ton has a short shaft with a bolt on yoke

it will still fit,just need to build a drive shaft with a splined slip yoke on it

I did that in a 68 Dart and SB short shaft bolt on yoke 727 from a club cab truck

my MH short BB 727 is diff mount location but with some fabing its in the 85 truck now,and I am building the dive shaft with a slip yoke in it
