'75 duster windshield gasket
I used the one's from Steele Rubber on my 73' Duster. I had the Gasket, plus round lockstrip. If memory serves both pieces were in the $175-200 range. Now, IMO the 73-76's were all the same shape n size windshield, the "tint" on the top may have changed from year to year, but that's all. So the gasket should be the same as well.
PS> Make sure you leave the gasket sitting in the sun for an hour, it will be much easier to work with :cheers:
