Hx35 bullseye question.

I've read that the bullseye housings that made the hx35 adaptable to our cars is no longer for sale. If you google "bullseye hx35 housing" you find some for sale for dsm guys. Does anybody know if these would work for our cars? The advertise a .53 a/r and with that, an hx35 would spool as fast as my little baby mitsu!
