1999 GMC® Conversion Build
The crew cab short boxes of this era are not the easiest to find. Locating a diesel one can add a layer of difficulty. So, when one shows up with potential but houses a 454-gas engine, instead of turning your cheek to the opportunity, you can roll up your sleeves and get to swapping.
