I had a whote top that was ...... up and i changed to black.
I kept the glass to save some money, but i had to spray paind the vinyl part of the glass. The place i got it install did it for me i just paid the spray paint($10)
The whole installation with the top cost me almost $400.
Everywhere else they've been asking for $650
You can get the top as low as $130 from ebay and just go for the install.
Look around and negotiate. That's what i did.
Good luck
