GM upgrade Alternator 1981 22R

Hi. Looking for tips and feedback on upgrading using LCE Alternator Bracket Kit (GM 1 Wire) setup.
LCE indicates their parts work with any of these GM alternators . Is there a standout choice I should buy , or consider them all comparable?
  • AIM/NAE (Napa) 67294
  • BBB Industries 72941w
  • Beck Arnley 1867294
  • Lester 7294se
  • Perfection 020854se100
  • Worldwide 53166
Also, I am a very much a novice when it comes to wiring projects, so wondering how difficult this is to upgrade. Is there diagrams out there with step by step instructions?

Thanks in advance

i put a 140amp gm 1-wire alternator on my 22re, using the trailgear bracket, it order to help power a winch that i didn't buy nor install until years later.

it was a bit of a hassle, not sure if wiring it for a 22r is much different... it takes it's own home run wire to the battery, i fused mine at the battery terminal with one of these fuse blocks:
Amazon Amazon

i haven't tested the setup under load yet, it's a powermaster alternator and the home run wire supplied with it is i think too small... powermaster no longer includes that wire, you have to add it yourself.
