This may help you out http://paintref.com/cgi-bin/colorco...nuf=Ford&smodel=Fairlane&sname=Snowshoe White Looks like 8097 for 1955 Tbird Snowshoe white
I have the charts for 1955 but they don't give the quan***ies for the mixing of the colour. The colour was only used for one year and i could not a formula for it. I went for Wimbledon White which though listed for 1965 is almost identical to 56's Colonial White I have seen US paint suppliers listing Snowshoe White for sale but I would have to get it shipped to Oz. Seemed too hard for me. Regards
