I'm in need of a port side windshield for my 88 272 SR1.

Del, sorry to hear about the windshield. I measured my 1987 242 ant the center windshield frame measures 22 1/4" on the outside from the hull to the top of the frame, if that helps.

I responded to your post in the swap shop.

Search Formula windshield in the search function.

If I remember correctly, all SR1 windshields are the same. The only differences in the 242 to the 357 is the number and size of the Side windows.
The front 2 are all the same.
If you find one, bring your piggy bank.
