well I got it in there but that didn't fix the problem, but my have helped. The old mount had about 1/8 in rattle in all directions. a few of the holes looked oval.
The good news: my new mount weights soooo much less than the stock one it came with. The OEM one was black and cast, I belive. The new OEM mount is silver due to being some sort of alloy. I think it is maybe half the weight. i should of weighhed them and compared. I might change out the other 3 and save a few lbs.
