Aluminum Wheels

[Droff]

I bought my '68 with the aluminum wheels in the pic and was told they were Duramax wheels. No reason for me to doubt it but I don't know much about Duramax wheels. I need some lug nuts and not sure on size, the ones I have now are a bit sketchy as far as fit goes but they've held the wheels on.

Any info on what year these wheels are or would that matter? I'd prefer lug nuts a little less large/long and have a few websites to shop at but I don't want to order something that won't fit correctly.

Also, I have a Dana rear with the stock drums, I 'think' the threads are 9/16"-18 but not positive. I have rotors from an '86 3/4 ton on the front now, what would be their size? The lug nuts I currently have will not thread onto the bolts.

Thanks.
