That old GM stuff, I can get an alternator for it for like 50 bucks.
My Nissan will cost me a good 150-180 bucks for an alternator, and that’s still me doing the install!
The new motor is on my 'to do' list along with a host of other minor repairs and some bodywork and paint, before I 'retire' it to pioneer vehicle status at 40 years old.
It won't be a commercial vehicle at that point, but one ten dollar set of tags and it's good forever (no annual registration fees).
It was a mere pup of seven years when I got it...
