I've looked through the FSM, my Haynes manual and searched forums on multiple sites. I can't identify this part on top of the thermostat housing and where the hoses are supposed to be attached.
Any help is appreciated. Thanks!
great looking car, I'm just starting my 75z to RB25 conversion, so I may have some questions for you :). My aim is similar to yours, street track, no drag or drifting etc.
