So i was at my dads work today and i was out in the garage where all the trucks are. He works for Verizon, they have a few older k30 4x4's. Well i was talking to one of the mechanics and i noticed one of the k30's they were working on. So i went up to it and i was like man i wish i had this truck, but as i was looking at it I noticed that it didnt have a dana 60 in the front. It was a 3/4 d44. Well long story short, turns out that 3 out of the 8 k30's they had d44's that someone swapped in. The mechanic said that someone must have done it in the last 2 months cause he said he serviced all the trucks front ends 2 months ago. He told the big boss and i guess they arent going to tell anyone else and just watch the other ones real closely to catch the guy, cuz its someone who works there. I kinda think it might be the mechanic, he seem kinda sketechy about the whole thing, who knows, wish i had one tho.
