42RH / A-500 in a Duster with pictures.
I'm curious to hear how the test drive goes in terms of the NVH level. I tried a similar design rear mount modification to install a long tailshaft 727 in my Duster and it made a wicked vibration harmonic at certain rpm's. Finally ended up going back to re-integrating the stock-type mount after exhausting numerous other troubleshooting steps.
