Thank you thank you!
Wow. Looking at the R/S tank & Associated Check valve (External; per the UPC 12 EN dated _Jan 5th 1968_) & filter, I was able to better understand the proper Config MY car should be set as (The Car was front ended in 1979 by previous owner) and they omitted the filter but kept the ORIG external check valve. So I was able to come to terms with this detail. I had a NOS (AC marked) filter in the drawer from Old Classic Camaro orders back in the 80's. Chick sincerely thanks for taking the time to post the pic's
As a side note Both my LOS cars (68/69) have the 1" washers on the hinges, Could it be a Plant -vs- Plant thing?
