differences in K-members

I believe your set-up uses the biscuit type mounts. My 71 Demon had them and I bought the conversion mounts from Schumacher along with their adjustable torque rod. Motor and tranny slipped right into place after notching the left mount as per schumachers instructions which come with the mounts. I used spool mounts years ago with another build and am now glad I stayed with the biscuit style. 2" TTI's also went in easy with this setup. If I were you I would just buy the conversion mounts that match the K member that's in the car.
