GMC GIANNI
Newbie
This is the upfitter's hand book for the GMT400 series truck. It has ever dimension you will EVER need for our truck. Everything from frame dimensions to the angle of the transfer case, to where the clearance lights are located.
This might be a good thing to sticky if a mod feels pleased to do so.
need to find a day at work when im all by myself and print this 120 pages off. Thanks for the link!!
