Power steering gearbox leak
Oh, I missed the 66 part
@GSXcite. I was still thinking '71, lol.
I bought this one for my '66. Not sure how original looking it is, but DMT generally take an original part and creates duplicates to manufacture. Mine was long gone when I got my car. I just wanted to keep heat and smells from the engine bay coming in the cab.
