Hicas Ca18det power steering help!

[chadbs13]

hey all, so ive got a 1990 240sx with a ca18det in it, it has the hicas pump on it, but of course my lhd 240 doesnt have hicas.

so ive done a little research and i guess the KA24de pump works so i picked up one of those from a local junker, aswell as the bracket.

now that ive taken a good look at it all, the KA bracket doesnt look like it will fit when i compare it to the ca (hicas) bracket. also i know the pulleys need to be switched, but the ka pully attaches by sliding into splines and then a bolt whereas the ca just has a little notch from about 12 oclock to 130 type thing.

so my question is has anyone with a ca with the hicas pump found a combination that works? any added suggestions or advice would also be awesome!
