I notice pro-source glass is again adverting after-market Europa windshields on ebay: $450 + $25 crating and $135 to $185 shipping (cont US). Pilkington Classic sells original spec windshields (they made them for Lotus) for $300 + $125 shipping (cont US, no packing fee).
I bought one of the Chinese knock-off windshields from pro-source and it didn’t fit, not even close. I contacted him right away and he did not get back to me until 3 months later. He made vague promises to “get a replacement to me”. That is another three months past now with no windshield, or further communication.
YMMV,
John
