Where to buy convertible top replacement kits
 

I own a 1990 RX7 convertible. Preparing to sell it but wondering if I should replace soft top, which has a tear near the back glass window. I saw a kit with black Haartz pin point, with 4 drainage hose shincluded, on convertibletopguys site that looked good. Any experience with this site? I just need soft top replaced but kit includes Targa, too. Should I replace both? Thanks for any suggestions.
