Default alternators, 10si vs cs130?
For my '70 Trans Am, I've been looking at the Powermaster 37806 alternator (200 amps), but it has the CS130 casing. I believe the stock casing type is 10si (this is what the Summit Tech Rep said as well).

Can anyone enlighten me as to how the sizes differ, whether anyone offers brackets, or just how easy it is to install a CS130 in a 10si car?

I've considered the simple drop-in units from HO Alternators, but if the Powermaster can be made to fit, it's much cheaper (and shinier).

Thanks
