Heavy Duty Alternator

arms are bigger and the depth is also greater. Since a lot of mopars came with the aforementioned delco alternators in the 70's and 80's, I would surely use one. You know those denso alternators are japanese and essentially a toyota part (toyota/denso/aisin/sumitomo are in bed together). The delco is a US part. I fail to see the difference in using one over the other.

I also have a lot of first hand experience with these alternators. I've owned a lot of GM cars (my daily driver is one too) and they work very well.
