I purchased these casters to build my car dolly for the purposes of repairing the rust and having the body work and paint done. As I never got to this point and since I have sold my project, I am now selling my (4) 12" casters. I paid $236.00 for all four and will let them go for $125.00 plus shipping. they are very heavy duty, swivel and will make rolling a 914 around extremely easy. Please sen me you e-mail for photos.
