About how much would it be to upgrade a 67 stang coupe to have power steering, air conditioning, and disc brakes? I'm just looking for a ball park here b/c I don't even know what type of brands of parts I want or are even out there. Thanks.
Assuming you have a V8 car, that you will need all new hardware, and are not interested in using original (style) parts I'd say a low end estimate would be $2.25K. Could easily run over three grand though.
