water leaking inside thru cowl grate

I’ve been chasing my tail trying to find the source of leaks in the front and rear of my 70 Dart Swinger. I replaced the wiper pivots but still have a leak or two in the front. I cleaned the cowl drains as best as I could. Based on this thread, I’m assuming it’s the windshield seal.

It looks like the rear is leaking around the window seal and where the old vinyl trim screws are.

Does anyone recommend any particular window seal product/company? I know there are a lot of cheap products out there so I’m looking to buy something others had success with. Thanks
