Hi to all, With regards to air cleaner housings, both the round crossram ones and the oval inlines, Club member Mike Laiserin makes very, very nice and authentic-looking reproductions - out of fiberglass. These come complete with baseplates, and would be a fantastic alternative to the steel units, especially for a non-concours vehicle. They are virtually indistinguishable from the originals, and are also very affordable. I just saw Mike's reproductions at the Chrysler 300 Club Inc's winter meet in Phoenix - they are truly superb ! contact Mike at mwl1967@xxxx for more information. John
