Hi Gil Thanks for the info; I was not aware that they used these air cleaners in 1956. Is that what you mean when you say "B "engine? Thanks Larry Jabin San Francisco <mailto:L.jabin1007@xxxxxxxxxx> L.jabin1007@xxxxxxxxxx _____ From: lettercars@xxxxxxx [mailto:lettercars@xxxxxxx] Sent: Wednesday, January 20, 2010 10:17 AM To: l.jabin1007@xxxxxxxxxx; chrysler300@xxxxxxxxxxxxxxx Subject: Re: [Chrysler300] 1958 300D AIR CLEANER Larry and All: The flat spots on the air cleaner housings are necessary when mounted on a "B" engine, as the carbs are much closer together. You will note the little hole on the flat side is supposed to retain a rubber bumper to prevent the housings from touching on "B" engine installations. As for the 300D, I consulted three of my old road tests. The car in the Motor Trend test has the flat portions facing each other. The other two, Road and Track and Car Life, have both flat areas facing toward the rear. Of course, any of these could have been changed by the testers, but kind of unlikely, I think. Anyway, seems like on the 300D you can put your air cleaners on the way you like! As for the decal position, all the early road test engine pictures agree: It is on the more gently rounded surface, with its inner (medial) end approximately at centerline and extending laterally. (Hope that makes sense.) So, if the air cleaners are installed with the flattened surfaces facing each other, the front housing decal is on the driver's side facing forward and the rear housing decal would be on the passenger side, facing rearward. Note: On the only factory photo I have of a "D" engine, the one on page 64 of Ackerson's book with Bob Rodger, the decal appears to be centered on the front facing surface. That is likely an early car, and is also an FI. Shall I go on? Well, ok. In the picture of the 300E with Bob Rodger, the decals seem to have "moved" more toward the lateral, more sharply curved surface. By 1962, the decals are centered on the housing "ends", so that the front housing decal is facing straight lateral towards the driver's side, and the rear housing decal is facing straight lateral towards the passenger side of the engine compartment. Is that enough? It is for me! Hope it helps. 300ly, Gil C. Tallahassee, FL In a message dated 1/19/2010 7:57:44 P.M.

Does anybody know how they were placed on the carburetors from the factory, if the flat spots face to the rear on both or do the flat spots face each other? I have seen it both ways Also where on the air cleaners do the instruction labels go?
