I got it at MPH for a 2000 jackal. The Jackal has a 4 piston caliper where the EV has 2, 2 piston calipers I,m told.rudyr
That's not correct. The California EV has two of the same calipers as the Jackal's one caliper. There is a right and a left. They are not interchangeable side to side.
As discussed here earlier, 1998 to 2001 they were model#5165
2001 to 2011, they were model# 6800
If you have a two piston caliper, it is from a 1997 or earlier California III or California 1100 and looks something like this, and will not be a direct fit to a Jackal:
