32krazy!,

Actually, I DID read all the previous threads pertaining to Polyurethane filling as well as about twenty threads and videos on how to make your own. Based on all the information I found about 80A durometer Polyurethane, filling these mounts that way is a real PITA and you will most definitely get air bubbles in them. The driver side one on mine is fine as the part that broke is like a key and will be retained by the Polyurethane just fine. Bare with me as this project unfolds. The mounts you sent are fine then. I will use them for about a month and be happy to pass them on to someone else in the forum for either a Polyurethane fill project or temporary holders like I'm using them for now.

And... you can NOT install them in twenty four hours! The cure time for 80A is a minimum of SEVEN days! Unless you want to try FDA compliant Urethane that cures in two hours but hardens in five minutes, then I suggest anyone who fills mounts or anything else with General Purpose Urethane make sure they go by the specifications and let them cure seven days.

I will be ordering my Polyurethane in the middle of the week and will be working on my jigs in the mean time.

BTW: In your PM to me about the mounts you sent, you said they were blown, yet above you said I should drain them. Which is it?
