I'm installing new quarters and trunk gutters on a 72 Challenger. It seems like the edge of quarter that fits over the trunk gutter comes down too far. The gutter cannot go any further forward or it will not be fitting with the deck filler correctly. Take a look at the picks. If possible, can anyone post a pick of this spot from their car. I'm thinking I may have to cut back the quarter a little bit but I'm not sure how much. Post pics please.
