Larger alternator, same plug? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The alternator on my 01 Silverado is taking a poop.

I'll be replacing it this week(400 mile trip next week, gotta be ready!)

On my older trucks I would put larger alts on them, their all farm truck, work lights, cb radios, and so on, just nice to have the extra power If need be, and I run large batteries in my trucks as well.

My truck has the 105amp alt(I THINK), will be doing a vin check today when I get through with chores.
Are the plugs all the same from the 105's to the 145's?
Would they bolt up to the existing mounting points?
Im ok with replacing what its got for the same thing, but just had to ask someone.

Thanks!

The plug should be the same as long as you get a alt for the same year as the truck.
