Modern driveline kit for me...
After crawling around under there, I can't imagine any of these being easy to install. This one was easy to setup, the instructions were good, but placing the components under that dash was a bear. This kit also has the upper end of the clutch lever really close to the dreaded cowl but does have some length adjustment. (I was also juggling a newly added brake booster and master cylinder, so that didn't simplify anything). I've been driving it for 6 months almost daily without a complaint. The cable routes all the way in front of the oil filter on a 289/302, some might object to that. It seems mechanically well thought out and well built. I have no experience with any of the others.
