I Found It
This process is mentioned in Les Andrews' Book, 'Model A Ford Mechanics Handbook' vol. 1, pp 1-278, under Installing Front Spring, item #3. It states basically as I described above. Except he said to "...glue the welting to the top leave ..." He did not mention the type of glue to use.
I think there will be plenty of people who have tried this, and can tell you if they would do it again. Good luck, Bill
