Hi John and All: I saw your 300C radiator question answered, but don't remember seeing anything on the two later part numbers you wanted identified. Their usage is: 2099903---1962 Dodge 880, Chrysler Newport, & 300w/std. engine Used with air conditioning only. 2099907---1962 Chrysler NewYorker and Imperial, used for both air conditioning and high altitude applications. Hope this helps. 300ly, Gil C. [Non-text portions of this message have been removed] ------------------------ Yahoo! Groups Sponsor ---------------------~--> Yahoo! Autos.
