I know that this question has probably been asked a thousand times already but here it is. I just got a lead on some one ton axles preety cheap and my main concern is are there any year of D60s that I should stay away from? There is a good chance that the guy that has these won't know the year of truck they came off of. any help is appreciated. thanks. MY K-5 DOESN'T LEAK... IT JUST MARKS ITS TERRITORY.
