I was going to ask for a picture of your hub cap – but by time I got my message posted, you already included a picture.
I would recommend you make a post in our “part(s) wanted” section with that picture. This is not the section for buying or selling.
I don't have a ’80 or 81 parts book. I looked in my ’79 parts book and found this:
Part # 3580408 (Volare only) – but the sticker in middle of cap is slightly different.
Most Chrysler 14 and 15” wheels will fit your car - all but the ‘60’s and early ‘70’s A-body’s which use a 4” bolt pattern instead of a 4.5” bolt pattern that all B, C, E, F, M, J, etc. body's use.
Wheels that came as options for these cars are:
Magnum 500 with trim ring and cap (official name is 14" road wheel). Parts are being repopped. Comes in various widths as well as 15" (repop).
Ralley (14"), with trim ring and cap. Parts are being repopped. Comes in various widths.
'80 (only) 14"x6" steel wheel, with trim ring and cap.
Aluminum 14"x6". I've seen silver and gold versions.
15"x7" Police wheel (with dog dish hubcap). These are repopped to just about any width or offset you want.
Super Coupe (F-body) 15" wheels. Almost the same as the Police wheels (above), except in silver and no provision for dog dish hubcaps.
10-spoke Aluminum. 15"x7". Used on J and M-body's.
5 on 5-spoke Aluminum 15"x7". Also M or J-body. This picture is missing center caps.
Snowflake Aluminum 15"x7". M or J-body.
