    The guy that built my engine also put the headers on. Not sure what brand they are. They work fine on the street, but as soon as the suspesnion flexes, the front driveshaft hits one of the tubes. It's already bent the tube in some. Are there different headers for 4 wheel drives so this dosnt happen?

    Most companies usually have a different listing for 4wd trucks. It's possible that the ones you have are for a car or 2wd truck. My front driveshaft rubs the collecter clamp but it's not really much of a problem, they are the cheap flowtech headers but are the right listing for my truck.

    <font color="green"> Mine's been rubbing for 3 years, but hasn't caused any problems. If it's isn't rubbing real hard don't worry about it. </font color>

    my 79 had heddman hedders on it. they tuck up higher then any header i have seen on a truck.. but with no lift i found out they do touch the front diff. but with a 4" when i had it ( i sold it with no lift on it) it was fine.
