I installed a Borgeson unit into my 62 and used a standard conversion U joint. Aside from needing to do a toe-n-go alignment adjustment, all good. No leaks no issues of note. Seems like a pretty good upgrade. We've see nsome teething issues with these as they came to market, so the best bet may be to have a professional shop do the install to avoid bricking your car for an extended period of time. I know that when I went to install mine I bought all 3 Pitman arms to aid the install and shorten the down time. I ended up using a stock arm since the 62's are single pivot idlers. Once I get the car back down for the next round of upgrades I'll swap the Idler to a double shear roller unit from Firm Feel and the quick ratio arm. the 14.7:1 that the box come with is nice but not as responsive as my Firm Feel Stage 2 box in my 68 with Q/R arms.
