15 x 6 YS Code Rally Wheel

[keith k]

I picked up a set of original 14 x 6 Rally Wheels for my '67 today, and got an extra 15 x 6 in the deal.  On the outer rim (would be inside the tire if a tire was on it) it says 15 x 6 JK.  The code by the valve stem appears to be YS, but the S is sort of faint compared to the Y.   The date code on the other side of the valve stem is K19 10.

Also, it's a 5x4-1/2 bolt pattern, and iit seems to have an odd backspacing of 3-1/2".

Does anyone know what this could be?

I found a reference to a YS wheel on the net, but can't find anything that says what application it was for.

With that bolt pattern, it's probably for a Ford or AMC application.

Oh -- Then I probably measured it wrong.  It WILL fit on a Camaro -- has same pattern as Camaro/Chevelle.

OK... here are some pics, if that helps.

Keith,

"YS" wheels were used on 69 Full Size with Disk Brakes and 70 Full Size (except wagons) with Disk Brakes. The wheel is 15x6 and has an offset of .06"

Thanks! 

Did the full size Chevys use the same bolt pattern as the Camaro and Chevelle then?  For some reason I thought they were different (but maybe I'm thinking of Pontiacs, and Chevys aren't the same).

Keith,

Yup. 5 on 4-3/4"

With a few exceptions, Chevrolet has used the same bolt pattern almost forever!
