What I did in here, I had a rear half of a Montero water pump, I removed the Eclipse pump assy, swapped the back half off from the FWD type to the RWD and reinstalled the assembly. No trickery involved.
Here is the front end back together.

And one more with a Thermo housing, Now I come to realize the DOHC thermostat is wider then a SOHC assembly. I am looking for a SOHC 24V t stat assy if there is one available?
