Why 2 parts #'s on Mach 1 alternators??
 

Question, if you go to Advance and look up alternators, it shows one for a

Auto trans

'''and one for manual trans

http://shop.advanceautoparts.com/p/t...999%7CL3*15587

What is the difference other than price?? (I did notice the the auto trans one said" Supplied With Clutch or Decoupler Pulley".

Would this one work for a manual trans Mach? Thanks guys!!

Resist the urge to buy from AA . I am fortunate to have a good local rebuild shop who is usually 1/2 to 1/3 the price of new on big truck alternators

The auto and manuals used a different amp alternator. I'm not entirely sure what the reasoning is behind it. I'd get the higher amp one regardless, some people even run aftermarket alternators rated at 170+ amps, to reduce voltage drop issues which eventually cause a lean condition.

I wonder if the 03+ crown vic p71 alternators would work on our cars. After some research I guess they switched to having a clutch type alternator to eliminate premature failures the older 130 amp models were having. The bullitt/mach alternators are also apparently thinner to provide clearance for the intake manifold, but since the centri's change the alternator location I wonder if there would still be clearance issues.

I just swapped the belt in my p71 and the stock alternator is 200amps. Ebay has reman and used ones for under $150. They both rotate the same direction, I'd image it would work.

The pulley is different and it doesn't stick out far enough. I bought a alternator and it turned out it was for a auto.
