It looks like the bearing setup from Firmfeel is retrofit onto the existing idler arm? How is it to install?
Rick Ehrenberg raved about it back in 2012.
You used to be able to buy them, but now we have the kit. They have instructions on that page so you can see if you are up to doing the conversion. It really is not a necessity. We used a 67 K frame on my brothers 67 Barracuda and put 300,000 miles on it, then swapped it into a 73+ car because that K-frame was toast. As for the fail safe motor mounts, it is fine to just add a torque strap to limit the stress on the LH motor mount. Add it to the head for a longer moment arm and to reduce stress on the block motor mount lugs.
