In 2009 when I had the engine pulled out I decided upgrade to the Centerforce Dual Friction Clutch Series. For this one, you will need a longer clutch rod for your slave cylinder. The stock rod cannot push the release bearing enough to engage the clutch. So I got a high school mechanic shop to make me a adjustable one that worked. The only problem with it was the diameter of to rod is to large for the dust boot. Running it with no boot lead to slave cylinder failure in 2015. On July 2021 I upgraded to king6fab rod and a mystery red boot.
I purchased the red dust boot from Italianmotorsusa.com . Shipping cost as much as the part, but it came in within 3 days. The dust boot looks small at first, but can be easily heated at stretched out to fit. Look at the comparisons. Works with all the sizes King6Fab clutch rods and the OE rod!
I used random tools and objects to stretch out the boot ends. Heated with a heat gun and let it cool back down and it will hold the new shape.
With stock OE boot.
You can cut the end like this one if you want to match the oe look, but I like the without the cut.
Garage Shop adjustable vs OE rod.
I bought 2 different sizes to try out. The 3/8 and 1/2 inch. The 3/8 is the perfect size. I think even the 1/4 would of worked great for my setup.

I did have to adjust the clutch rod to get the right feel on the clutch pedal, but with this rod I can dial it in close to OE position.
