Just gotta set of rally wheels for free, is there a number on them to identify them? I'm just curious and want to know what they came off of.

 

Theres a dot code and size stamped on the inside of the rim.

 

There should be some code numbers (letters) on the insides, as well as the size.
Post them and maybe we can figure it out. Not sure if all wheels had the codes...

 

Do the rims have tires on them? The codes are usually stamped on the inside of the rim that's concealed by the tire. If they don't have tires but have sitting around a while, the codes may be obscured by rust or grime. Should be something like 14X7 JJ. There may also be a date code. It may take a wire wheel to get the crud off so you can see the codes stamped into the wheels.
There used to be a chart in the year one catalog that showed the various wheels and codes used through the years.
