and for a driver, a Wix #33041 listed for 71-73 chevy may work. it is 4 5/8 long, and 2 1/16 od. 3/8" in and out with a 1/4" return. i can't say if there is any restrictor or screen in the return because i don't have one to look at. i found this in my Wix master catalog. just something else to ponder.
