Hi John, welcome to our group.
For your 1998 Sun Voyager 60X74 bedspread, the company you would want to contact is:
Decorator Industries
1614 Eisenhower Dr, N
Goshen, IN 46526
Phone: 574-533-8641

I have no way of knowing if GS used them for the '98 models, but it seems likely. That's the good news.
The bad news is that you may need a 2nd mortgage on the house to buy it, or at least willingness to give up one of the kids.
Other forum members have attempted to purchase original equipment soft goods thru GS, only to be quoted outrageous prices,,, I mean
OUTRAGEOUS! That is likely because Decorator Industries continuously changes their material patterns & GS has no inexpensive way of providing you an old pattern. It would be worth contacting the supplier however, to see what is currently available, & if/how you might purchase individual pieces. (as opposed to a hundred - WOW!)
They may be able to tell you what alternate to buy, of their same quality, at a retail establishment (such as previously mentioned Camping World).
Good Luck & let us know how you make out.
