I have found the part number for a 2003 tag air spring or air bag, if you will. But I do not know if that part number is good for a 2001 and a 1998 coach. Anyone have more info on these air springs?
Pre 2003 is likely different. The parts list shows the bag for the 2003's started with coach 6059.
2002 tag did not lift so tag mechanism is different pre-2003.
