Ive installed that retro kit
and it was a pain - very little room to work with so fitting the 1/2” to 3/4” adapters on both ends wasn’t easy or pretty. Took at least twice as long as I expected, although I was on the road and away from the “Mother Shop”. It worked and I was in NH headed for Maine, so I was glad to have the thing fixed, but I wouldn't use that kit again if I could avoid it.
I would advise reading this before ordering to help decide if it's worth it to you:
