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.

I hope to know Wednesday if this week goes well- I spent yesterday afternoon doing some final work to the case (seals, tapping threaded holes, new fasteners, band adjustments) and getting ready to tear down the valve body after reviewing the shift kit instructions which I purchased 6 years ago for my Durango!
