will my t-tops from my bird fit in a t-top bag from a 68-82 vett They look the same and have the same clips, or atleast they do in pictures.

also what years did the zip ones come in and what years did the flap velcro ones come in. I have a velcro one I got a while back but would like to have a better one.

 

I dont know about all cars, but my 91 came with a zipper. I would venture to guess that older cars had the velcro.
