ARH question
1. You eliminate the EGR.
2. You get the metal tubes at the end of the AIR lines from someone that has a 2000.
I wouldn't mess around with welding the hole and drilling a new one.
if your good at fabricating you can just make an extension and buy 1 extra egr gasket, havent seen how far of a diff the 99 is from the 2000 though. or maybe getting an egr tube of a 99.
