Method 701s on 80 series

[Shaquille Oatmeal]

I'm looking to put new wheels on my 80. I've wanted to go with the 701s. From what I understand, they require the center to be machined out to allow enough room for the hubs. Does anybody have any information on what measurements I'd need to provide, as well as where I would want to go to have that work done?

Also, wanting to double check the size I have is correct for the wheel (as pictured below). 17x8.5 6-139.7 0 offset?

@Ozark cruiser can provide more info.

I believe it’s the center cap bore that needs changed to clear the hubs.

Any competent machine shop with a lathe should be able to handle it.

I had his done years ago. I believe I had the center opened up 4-5mm?
Pretty easy to measure, there is no guess work!
