Hell, 6 spider gears? Sign me up! Where can I retro-fit one of these into some savage bulkheads? Lol.
I would go for that, if it's a direct drop in. Well worth $155, IMO. That should be a one-time deal as well. With 6 spiders, and apparently Incredible Hulk inspired bevel gears, you should be good. All the options I have for the Savage is just replacing the diff gears with the ones from the HB Lightning. (I have, and there's a very slight difference between the stock BP gears and the HB gears. HB is thicker, and is hardened steel like the BP ones)
