[Amps] Chimney for 8930

[Byron Tatum]

Hello-
    Does anyone have the chimney for the 8930 / 4CX400A ? I need some of the type that rest on the socket top surface { SK-620 / 630 type socket} and come up and cover a portion of the anode cooler {the same as the 4CX250 types}, believe there is a Johnson part #. I would buy new or used ones if available, or trade the ones for 4CX250 series at a ratio of 3 to 1{ Used ones I have, but nice}.
        Thanks, WA5THJ.
