3 shift linkage upgrades, my installation/driving impressions (long)
Spherical rod end linkage is very little improvement over new stock plastic ball-in-socket pivots, since there is little/no play in the stock setup.
The biggest improvement in the shift linkage comes from putting solid, low-tolerance bushings everywhere you can replace the stock polyurethane units, which quickly go south from oil/heat.
I put the complete MissingLinkz kit on mine (minus the weighted link) and found the above to be true.

This sounds great Cathy... I've been wanting to upgrade the shift linkage in my Mk1 again and
could use some advice. Sounds like the 'Scott Rose' setup was the best... maybe Scott could tell
us some more about this setup... I recall hearing about it, but never heard the details.
You might have to take some pictures for us... or better yet I'll just crawl under your car in a
few weeks at track day north. ;)
Thanks for your report!
