I have a 1967 Coronet and it has light pinhole rust in the lower quarters behind the wheel arches. I'm also going to replace the trunk extensions behind them and I'm wondering if anyone on here has done the job and can rate the quality of the parts they used. There are a few manufacturer's of these out there and the prices vary. I've done prior metal replacement on other cars and found out the hard way that brand name doesn't always mean good fitment. Some manufacturer's sell some great parts but also sell total garbage. I'm wanting the repair to look stock. Quality is priority over price. My plan is to only replace the lower three inches so there won't be a visible seam in the trunk. Any advice from someone with experience would be greatly appreciated. Thanks!
