Installed one into my 62 about 4 years ago, daily drive that one and it was fantastic, all the previous issues were gone. Dropping one into my Road Runner now to replace my Firm Feel stage 2 that sprung a leak after 14 years of faithful service.
I posted in another thread, the current Borg boxes are 12.1 lbs lighter than the stock boxes (stock box is 35.9 lbs on a certified scale, Borg unit was 23.8). That is a lot of weight off the nose.
