1968 T top noise
My new project. To make my 1968 T top quiet. It isn't to bad,,,, but I would like my T top to be quieter. Going over bumps I do get some rattles. Seems like I get a rattle from my rear window also. Any suggestions?

I had two new C3s 73 and 78 and a 72 I bought with only 6500 miles from new in late 1972, all three T-tops would rattle going over a railroad track, frame flexing causing it. A 68 frame is same as 63 to 67 frames does not even have the extra supports for the rear kickup rails that 69 up have.

There are two plastic bushes in the t section and one in the front corners of the windscreen that you could replace to help stop the rattles ,and you can shim the t top metal tabs to make it tighter

Advice as above. Also take your tops off the car and shake them. I had debris inside the tops.
You may want to replace the weatherstrip to snug things up. That's a fun job.
The rear window latch pressure is adjustable and weatherstrip might be a solution there too.
