Or do what i did and buy them and swap the white faces to your dials you have in the car now
I think he means just fit the dial faces to your existing clocks
I take it the Cupra dial mat is from a diesel Cupra and has the same Rev range and max mph as your own? Like Lee says it should be straight forward other than getting the needles back on/off accurately. However there have been some horror stories of late so maybe not a bad idea to stick it in the garage. Of course, you could always go for custom dials
