What size rims did they make??

[67chevemall]

Hello

I need 15X8 rims made after 71 for my front disc conversion.
They are had to find with the hub cap knobs facing up and out.

I found a few with the knobs facing in but then you have to use aftermarket caps.

Did Chevy make them 8" wide or was 6" the normal?

Does anybody have two of 15X8 if so made?

My 67 Rims were custom made to 15X9 and I need to replace them to fit over the disc brakes.... Has anybody grinded the 67 rims down to fit?? I tried a little grinding but I think it would take a lot...
