Can someone explain to me the method that honda uses to create part number or engineering numbers for their parts ?

I was looking at some factory wheels the other day and they listed two part numbers. Only difference was was the last number.

For example - the last numbers were 100F and the other number would have been 101F. The wheels look identical. Someone told me that it was rather a different "shift" or a different manufacturer that made the same part....

I am typically from the Ford Fox Mustang world, so I am new to trying to decipher honda numbers.

In the ford world the first 2 characters annotate a change in the year. You could have two identical "looking" parts - one that begins with an E5 and one that begins with an E7. The E5 desigantes a 1985 engineering number and the E7 designates a 1987 engineering number. So there was a engineering change in 1987 (hopefully to "better" the E5 part). But that is the way Ford does it....

Thanks,
Jason
