You can buy a new windshield through any dealership or the Classic center. Just take with you one of the following part numbers:
Given that you have a 230SL, it would have originally been delivered with a clear windshield, part number 113-671-03-10 , still available, wholesales for $395 and retails for $500. Being in Miami, and if you're not too concerned about this aspect of originality, you may want a green tinted heat absorbing windshield. Part number 113-671-04-10, currently retails for $398 and retails for $680. There is a third glass you can buy that i also heat absorbing, but I'm not sure if it's clear or bronze tinted. Part number 113-671-02-10. It wholesales for $318 and retails for $520.
Regarding the trim and seal, there are a total of 5 pieces of trim that you'll need. The left side, right side, and the two little joint covers that mate the two halves. The left side trim, part number, 113-671-01-30, is available through any dealership or Classic. It wholesales for $255 and retails for $354. The right side piece of trim, part number 113-671-02-30, is still available through any dealership or Classic. It, too, wholesales for $255 and retails for $354. The two joint covers, part number 110-678-04-37, are also still available through any dealership. They wholesale for $18 each, and retail for $18.50 each.
The rubber seal, part number 113-671-02-20, is also available through any dealership or Classic. It wholesales for $118 and retails for $147.
I make mention of all of the wholesale and retail prices due to so many dealerships, private vendors, and even Classic often charging more than retail.....which is bad business. So when you go to buy your parts make sure the prices quoted to you fall within the parameters in mentioned in the prices stated above. If you go to a dealership be sure to take the part numbers with you, as most parts personnel will claim they can't get these parts.....but mostly because they have no idea how to look the parts up or even know that a Pagoda is still listed in the electronic parts catalog.
