2007 x350 VDP Donut spare
 

Hey all. I have the above car as a donor, and want to eventually sell the 18" chrome rims and tires, (looks like they are those universal jobbies with the plastic center cap) but I still want to be able to move the car around, and am looking for a CHEAP wheel alternative and found a few old Donut spares kicking around, but can't seem to find any letters/numbers on them showing if they would fit. (I have yet to try them on the car but of course they are various sizes) I'm thinking the wreckers shouldn't want a lot for these type of wheels? I have tried Ford aluminium rims, since I have a set of those, but they didn't clear the caliper. Any help to point me in the general direction is appreciated.
