Can someone send post a link that I can use to check the codes stamped on my Rally II Wheels. They are off a 1969 Firebird. I'm not sure if they are original. I suspect they are not as two of them are 14x6, three are 14x7. the 14x7's looked to be GM stamped JJ. I am having a hard time reading the 14x6's.

Disregard this note;

Note: one reader has reported that 'KS' wheels are incompatible with '69 Firebird disc brakes

It is incorrect.

I just looked at 2 KS wheels side by side with some JS and JK wheels and they look to be identical. Just as a side note...

Garz can you have a look at the left and right side of your valve stems. You'll see a small stamped "M" with two same sized numbers close by which indicated the manufacturer code and year the wheel was made then closer to the left of the stem will be a larger number which gives the month. To the right is another number indicating the day then farther to the right is a two letter code. JK, KS, JS are all 14x7 but from what I have read JK was produced earlier than the other two and would be correct for your car.
