i just ordered new fenders for a 99-00 as i got into an accident last week and am doing a total 99-00 conversion and would like to get jdm ctr sidemarkers to go along with it all.. Are they hard to drill into metal fenders?? And once they are in what keeps them in and what would you seal them with? silicone? Not too bad with bodywork and have an idea but any insight would help.. also whats a fair price for them? much
