Hello Camaro fans, I am currently restoring a 1969, I installed DSE mini tubs and new OER quarters, The qtrs seem to fit well along door edge and everywhere except the trunk gap, it is wide like 1/2 inch, anybody ran into this problem, starts out closest to back window good then gets wider about 1/3 of the way down towards rear panel any help would be apreciated Thanks
