I only speak of the experiences I've had with Superformance. I have owned my SPF since 2002 (#1358) and have worked in a local shop that does the engine installs and final assembly and delivery of these vehicles for an SPF dealer. There's a fairly large SPF contingent here on Long Island and I have been around these cars for four years now, I have replaced numerous windshields on SPF's ( all later then #1300) so they all had support rods. Some had the rear view mirror on the cowl and later cars had them attached to the support rod....
The newer cars , starting somewhere around #2000 and I can't remember exactly had no support rod and bonded glass, although the newer glass that is now bonded is of the same shape and the rear view mirror was attached to the glass directly.
I am member of SCOF (Superformance Cobra Owners Forum) and windshield problems have surfaced from time to time, SCOF keeps close ties to SPF and if there was another change to the body shape there would be yet another windshield....If im wrong I'll be the first to admit it, really.
There should be no difference between the shape of your #1350 and Chris's#1750 and they both use the same frame and glass and the body has not changed. If someone along the line changed an original SPF windshield frame for lets say the current aftermarket there will be discrepencies. A while back there were SPF glass shortages and some of the guy's changed entire glass and frames to non SPF due to the shortages.
I'd like to here more of the differences of your cars and who told you that the glass is different ???
