CK, I would recommend that you make contact with Classic Auto Supply Company, Inc. in Coshocton, Ohio.
They've produced a series of videos to assist hobbyists in various aspects of maintenance and restoration of '55-'57 'Birds. Their DVD titled, 'Recovering the soft top' is part no. CV1 and is priced at $19.95 plus shipping.
CASCO has been dealing with '55-'57 'Birds for 45 years, initially in parts supply, today in reproduction part production, vehicle maintenance, AND full vehicle restoration projects. It's a second generation operation now with Bill and Sue Brown's son Jim and daughter-in-law Betsy running things. They have 14 employees as of last year.
Their Internet website is www.classictbird.com
Their email address is
casco@classictbird.com
Their phone number for international orders is 740-622-8561
Their FAX number for international orders is 740-622-5151
I've always been very satisfied with any purchases I've made from this business and their handling of orders. Those that I've recommended this business to have always reported that they were happy with their dealing with them as well.
Hope this helps.
