I put glass fenders on a mg b and you have to have patience . They don’t put the holes in because they are made from moulds and They are not like the steel fenders thicker and fitting them is a chore. I think if you were doing it yourself and took your time you could make them look okay but if you had to pay labour for installing them I think it would be cheaper to have metal fenders in the long run .I would line up the fender with the door and hood and only put a few holes in first before drilling all of the holes
