I just got one of Silverrotors last FD alt into FC kits and I tried to put it on with another forum member last night but it seemed the S4 mounting and pivot bolts were too short and too small respectively. So I was wondering if anyone else who has installed one of these kits successfully could let me know what size and bolts are needed to install it. Thank you!

 

I just used the S4 bolts, odd.......

 

Yeah the pivot is just way to small, it won't thread into the alt at all. And the mounting bolt appears to be too short for comfort.

 

Do you mean the pitch? Pivot?? Huh?

Are you sure you have the correct bolt for your alternator? I have used the same bolts for the s4, s5, s6, and even cosmo alt...

 

I'm not sure if the bolt was changed sometime before I got the car but it held the stock alt that was in the car.

 

the one i installed the long bolt fit fine and used a longer normal sized bolt/nut for the pivot mounting from the hardware store.
