the year is kind of hard to figure out but the title and vin say 79. so....
anywho, it was pushing 40's in that picture with a 14 bolt FF and dana 44. after snapping a few front axle shafts (even with 38s) i switch to a locker and havnt had any more issues with the axle shafts "knock on wood". ive also ran 44s with no issue after the locker. setup is 350 465/205 and 4.10, i used to run it on the streets but i took it off because i felt like it was a danger due to the frame being cracked and bad brakes. could be fixed but i have too many trucks now on the road so she'll stay on the dirt roads for now
