axles off a 78 250. what is it? 4 10, assuming 4 10 gears. 4 10 edd7 ta al
603901 -5
common, tell me its a 70. thanks guys.

 

Chrono are you asking about both axles or just the rear if it just the rear it's probly just a D60 in just a F250. I think D70 were found in F350's and up now i can be wrong.

 

that id is just the rear. i know that 60s came in base 250's, but a 70 could be had.

 

Yeah it would depend on how the original owner ordered it from ford.

 

Anybody know?

 

where'd you find those numbers? on an axle tag?

it sure looks like a 70 but like i said its ahrd to tell in just a pic

here make sure your numbers match up... http://www.supermotors.org/vehicles/...512&original=1

603901 FORD 60 REAR 1979 F-250 4X4 - FULL FLOAT
