From time to time forum members have inquired about replacement/additional pads for the Garelick motor mount (original equipment installed on P18 and I assume same on P21 and P23. not sure about P165). Lo and behold, I have uncovered one that I salvaged from my first P18. It is that black poly pad, about 2 inches thick, a little more than 9 inches wide at fat part and a bit more than 10 inches high. Multiple holes to line up bolts (bolts not included). Weight is 73 ounces (aka 4.6 lbs). These things are pricey as I recall ($70-$80) but yours for whatever you want to donate to your favorite charity, plus shipping. If you want it, let me know!
