Part numbers for rebuiling SR20 Alternator - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Well I ended up pulling it off...

All the parts listed above fit perfectly in a S13 SR20DET alternator with the B post being in the back of the alternator and not out the side.

The downside, the B post is now 5mm and should be a wider post. There may be another rectifier out there that has a wider post, you just need to hunt down the right part number. Then again, you might not even need the rectifier, I just replaced mine for the hell of it since I had it apart. Most of the time it's just the regulator that is busted so you might just replace that at a cost of 20 bucks and some time.

Hope this helps some out
