(2) How do I verify fitment for my car?
Open your engine bay and find the commission number plate on the bulkhead (firewall) below the spark plugs. If that number is greater than TS41742, the top is a proper factory‑style match. If unsure, you can email your VIN or commission number to TopsOnline for confirmation before ordering.

(4) Can I install this Convertible Top myself?
Technically, yes, most people can manage to install a Convertible Top on their own, provided they have experience working on automotive upholstery projects. However, TopsOnline.com recommends using a professional installer. Why? Because (a) a professional is going to provide you with the very best convertible top installation that you could ask for; (b) in the rare case where an installer might make a mistake, they’ll take care of it – but if YOU make a mistake with your own installation, that’s coming out of your pocket; and (c) finally, manufacturers reserve the right to void a warranty due to a faulty installation when that installation is done by someone who is not a professional installer. So bottom line: don’t take the risk: hire a professional installer for your convertible top installation – it’s worth it and you won’t regret it!
