Had some awesome weather so been messing with my 4 wheel purgatory machine. The brackets came with a CS130 105A alt. I have a new CS144 140A alt I would just love to use instead. According to GM, 130 and 144 can be easily swapped and have the same mounts, yada yada yada. I beg to differ.
When the original 105A was installed, it had a bolt in each ear and a support bracket that went from a boss on the back of the alt to an exhaust manifold bolt (with a spacer). When I swap in the 140A, the outer side lines up fine; the inner side hole doesn't quite line up (not to mention there is no boss or support). I get this:
I could egg shape the hole - not crazy about the idea, but can. There would then be alot of weight on a single ear of the bracket. Then might have to fab something to help support it. There is a boss on the back - very large and no idea what size - but in an awkward area. Any bracket will be a mess to make.
Any suggestions?
Here they are side by side.
