i have the parts but they are still in the car and if i take em out then water will get in so i need to no before i start.

Yes, according to VB the '70-'78 windshield are all the same and have the same part number.

He is correct, the front glass is interchangeable 69-78 the other glass is not as unversal to the S30

I hope you have a new gasket !

they should have them . Check with midwestz first and see how Chloe's prices compair . Check Motorspot as well. I know they are spendy , around $100.00 I need one also but havent priced them yet. Gary
