I purchased a McLeod unit from modern drive line . After fighting it for a year and pulling trans several times I spoke to modern driveline. Bruce said. Ya we had a lot of problems with those and no longer sell them. If you don’t like it talk to McLeod. They were equally helpful. Ended up giving it away and going external . Unless they have improved. I would not recommend McLeod.
Mine worked good I also had a Mal Woods under dash master cylinder. Only problem I had was the heavy clutch pedal that was more to do with the clutch and under dash pedal box ratio. I also had to run a spacer plate between the box and the bellhousing it was around 2 to 3mm thick.
I ended up swapping to C6 due to my father not being able to hold the clutch in at 73 years old.
But I will swap back in a few years and get Mal woods to fix the pedal ratio and or change the clutch to make it more user friendly.
