Convertible top for a Vintage

Hi,
Is anyone aware of a convertible top/side curtains retrofit to a Vintage Spyder. I am trying to find out if this is possible. I know Beck's have them, but not sure about the Vintage. Any information would be helpful, especially from someone who has the setup.
Thanks.
David

I have retro fit our top onto a Vintage car before.
Mounting points for the back of the top, posts, and side curtains were easy. Catches in the windshield frame were a pain in the a$$!
Would probably be easier to change the complete windshield assembly, including the lower track. Just my $0.02

Carey IS da MAN for the top situation. Do talk to him. He is a super guy and will not give you a wrong steer. IIRC, there may have been a recent thread on www.Spyderclub.com. If you are not already a member there, please join up. Great bunch of people with an incredible amount of knowledge.
