purchased new glass top due to broken top. But looks like there was a gasket on old top. do i need to get a gasket and are there instructions on installing gasket on/with top. haven’t removed complete top yet. does gasket fit around entire top inside of trim? 
Most times a replacement glass will come with its gasket already installed on it but if your particular one doesn’t come that way, yes, you’ll likely need to order a new gasket as the old one likely won’t be able to be reused. :rolleyes:

The gasket usually goes directly onto the glass all around its edges and then the trims just get pressed over it.
