looking for information on the right direction to go with my cougar.my cougar is a 1967 xr7 gt all original 390 4 speed posi rear vinyl top in very nice condition with 22,700 something miles. always wanted one since I first saw them in 1967 the year after I graduated High school. I wanted to drive it, so I have been working on it.I have been Welder Mechanic all my life(still working).I think the car is pretty rare. 1 of 905 with engine and transmission codes, Was in garage or barn out of the weather most of its life. This is my first post on this forum? I am from Suffern NY later.
