Thanks everyone! My mount I grabbed from Advance Auto I was unsure if it was hydraulic or not, and couldn't hear any fluid. The sales rep said since it was cheap compared to the AC Delco one that it was most definitely solid. I drilled the two holes last night and surprise surprise it was full of fluid. I drained most of it, will try to flush it with brake fluid today. I see that the Loctite PL Premium Construction Adhesive has been suggested a few times? Is this a good and viable solution or would I be better off with the more expensive Window Weld stuff from 3M?
