Glass Identification

Need some help with a windscreen (windshield) glass. Came from the UK and was supposed to be for a 250GTE, but clearly is not.

It measures 17" from the top to bottom at the center of the glass.
Also if you follow the upper edge of the glass top corner to top corner following the curves it is 44.5".

It would appear to be from the same era as the 250.

The tag on the glass says: "FX652T" It is a Pilkington glass.

Thanks

 

I think a photo would help.

 

I am told that the pilkington number should start with a FW for foreign windshield. FW652 comes up as fitting a Jag sedan. It doesn't give a year just that description. I am also told that the pilkington # for that 250GTE should be in the 300's.
