Matt,
I may have what you need.
I converted Sierra to Cleveland's last year and have the original McCauley's in my hanger with the old tires still mounted to them.
I have not had them apart in years as I've only serviced the wheel bearings at each annual and that does not require the wheel halves to be separated.
My serial number is 15279996. If the part numbers you have apply to my serial number you're welcome to these.
I really should dismount the tires and look them (the wheels) over for corrosion and cracks to make sure they're okay. One never knows what you'll find.
Jim
