Value of 67 Olds 442

[dkatap]

I found a 67 442 today. It is a complete original car with original drivetrain. The car is a factory 3 spd. My question is, does this hurt the value? I have been told that only about 400 were made with 3 spd. The car needs a complete restoration, but it is all there. Some rust, but not alot in my opinion. The worst is around the back glass. It has a 12 bolt and the frame appears solid, I will know more when I get it out of the weeds. Thanks for all opinions on value and desirability.
