GT5 and GT8 are ratios, not axle models, im sure you know that, i said it anyways
and i see more 14 bolt duallies than dana duallies big time, i ive only seen two or three dana dually trucks ever, everything else has been 14 bolt
dana was only under some 80-up dually pickups i know, yeah, i have gm specifications sheets showing illustration of them and listing 70 axle and rear bar and all,. 3+3 cab
apparently some running around now were originally not pickups or something

If you read carefully on the GT5 and GT8 description, GT8 is the HD.
The only difference between D70 and the 14bff is the axle tube diameter, and the D70 in dually form is the HD.
That led me to believe that the GT8 is the D70 dually.
Why else would they have 2 codes for the same ratio.
