Finally got around to putting in the Rauch & Spiegel coupling I purchased and it is so nice to have crisp shifts. Here's some photos of the temporary repair after I removed the old coupling. My jerry-rigged shift bushings performed remarkably well for 3 weeks! Best part is they were put in place without removing the coupling. A nice 20 minute fix to get home and buy time until the new coupling arrived.
3/4" OD vinyl tuping and 5/8" copper
And some tape and hose clamps to hold it all together
