Adjustable End Links
What you have there is somewhat of a fast shuffle. What's offered is a set of 'modified' Heim ends with little rubber booties on them. I'm sure that I could duplicate their function from the bins at any worthwhile machinery hardware shop and not have more than $25 in each side. The last time I did that sort of thing, I built a new clutch linkage for my '63 F-100, all the way from the pedal under the dash to the throwout fork on the bell housing. I had less than $10 in it, but it was several years ago.
