I have 2 of these. 1 for 4 years and 1 last year. If you order it from ebay it is free shipping if you order it from there site it is $15 extra.

Nice find! I think I will upgrade my gen V 502 also since the engine is apart right now and the alternator is ez to get to. What is the stock out put? Something like 60 amps?

Careful when you go over the 105amp. Your charging system might not have large enough gauge wire for 130, 150 and 175 amp alternators.
Remember your original system was only ~60amps.
