Hey guys,
1994 K1500 GMC 5.7 Z-71
Getting rid of the worthless CS130 alternator and upgrading to an AD244 for all the obvious reasons.
I've bought a genuine GM (supposedly) AD244, # GM 15279852, 145 amp alternator that supposedly fits GM vehicles from 1996 to 2005.
I have about 4 various forum postings here, and 3 or 4 YouTube videos showing and stating that there's just a "slight" mismatch on the one, inboard mounting hole. Some show just filing the hole oblong to fit, with many just hogging the hole out a bit with a drill bit. The mismatch is variously stated to be anywhere from 1/16" to 1/4". Some even say if you are willing to just go to a smaller diameter bolt, that will fit up. The mismatch is so slight that a smaller bolt will fit the holes.
THEN, there's MY case. As you can see from the pics, my mismatch is huge!! It's more like a 3/4" mismatch!
So, mine is a standard CS130, and I am swapping to a standard AD244, just like everyone I've spent HOURS researching. But see the pics, and the mounting mismatch I've got!! What's my problem here???
Thanks!!
