I came to a thes in the 80s my parents bought it new in the car trailer, IÂ'm looking for another, you need a 318 and tops of 4 Speed Stick T are optional. Black would be good to see some pictures and found one that I suspect are made poorly or rarely (not) any links or information would be appreciated thank you
