Ok, I promise I did my best to find the answer to this, but no luck. I have a 1980 HJ45 with the H diesel. I notice when I price Clutch kits for it that the "H" kit cost waaayyyy more than the 2H kit. My question is, are they interchangable? In my search, I heard several people talk about how the "older style" clutch in the H was sub-par to the 2H. Anybody else have issues sourcing this?
