Back around 2011, I purchased a rear disc brake conversion kit for my 1973 240Z, but I can't remember where I bought it from. Supposedly it used the calipers from a 240SX. One of those calipers is now leaking. I got a re-man caliper for a 1998 to 1994 and it doesn't fit. (See picture 1)
I then got a re-man for a 1995 to 1990, and it's closer, but still not right. (pictures 2 & 3)
Any idea as to what I need ??
