I owned one 1969 RoadRunner or another everyday of my life from September 1969 to May 2015. I can tell you every bolt marking and spot weld on one! I had one each in a yellow gold, sun fire yellow, ivy green metallic, black velvet and platinum metallic. The yellow gold and the ivy green ones were 383 4 speeds. The others all came with more than one carburetor. Great cars and why I love my Mopars!
