The set listed above on eBay......
I believe are for a genuine 430, and will NOT fit the DNA 430, without alteration.
So a lot of money to be cutting them apart, in my opinion.
Everyone’s roleover hoops will be slightly different in thickness due to the amount of padding used when they were trimmed, and what thickness of leather was used.. so bespoke items will need to be designed and made, as far as I’m concerned.
Like everything with these cars, most things need to designed, made and fitted, as there is limited items (off the shelf) that fit.
