67 Cuda 1/4 panel help.

Dang it....My lower quarter behind the wheel on the drivers side has a few pin holes.So who makes a lower quarter patch?I can not find one.
Also I am replacing the trunk extensions.I bought AMD Duster extensions.Anyone have pics on how to modifiy these to fit?Or advice on how to do it.I am sure I can figure it out.But tips on how to do it will help me out...

Oh this is on my 67 Formula S...Thanks,Jim
