OEM rim part number

justjoef · June 16, 2018

I need to replace a couple, if not all of (what I assume to be) the original rims on this (1997 GMC 2500 SLE Extended Cab 5.7L 4WD) truck. I found what I thought to be the proper substitution. However, while it supposedly fits the truck, this is a portion of the description...

"This product fits 1997 GMC CK Pickup, but replaces the following OE part # only (may be found out from your dealership): 560-01619, 11015741, 85-01619U20, 9592422, GF93UN9185FV, STL01619U20R, X45307."

Things I've tried: Rock Auto also had a list of 8 different part numbers. LMC only had custom wheels. Ebay would probably work fine if the truck wasn't so old. No listings for rims for my truck.

I'm just a shade tree mechanic and don't understand why there are 7 different part numbers that this truck potentially has for rims. I popped off one wheel hoping to find the part number. I assume it's on the inside of the tire portion of the rim, as I could find nothing. However, these rims are rusting out badly, so it may just be illegible. Is my only option really to go to the dealer? I imagine they don't want to waste their time looking up a part number for a 20 year old truck, knowing I won't be buying brand new rims from them (which is completely understandable). Any help would be appreciated.
