I know the exhaust is different on the passenger side because it makes a U around the transfer case. Not sure if the headers are any different. Look at Summitt's website and see if there are different part numbers.

buy the headers that fit what you got, and not take a chance, or find the part number and make sure it fits.

I say this because we had some dynomax blackjack headers bought for a 76 2wd stick shift, and they fit a 86 k10 4xd4 auto perfectly. The exhaust had to be made to work but almost anytime you go from manifolds to headers that is always an issue.
