Agreed. There were some serious issues with the first run of these boxes, but I think they've got them sorted now for the most part. I haven't had an issue since the first one(first gen) I installed for a customer, it had the input shaft/column alignment issue. We also had a few that would back the pitman arm nut off, despite 2 retorques. KInda weird, almost like the splines needed to bed in.
HOWEVER, the last 2 have been great. 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.
