What's the attack bonus on this attack for a 9hd spider? And: Is there any 3.5 version of this spider, besides the updates in the PGtF web enhancement?

I know it's strength, and it's size. A normal sword spider: BAB: +3, Strength bonus: +4, size: Large (-1 attack bonus). Impalement attack bonus: +5 (I don't know how this number is figured out). My spider: BAB +6, Strength bonus: +6, Size: Large: (-1 attack bonus), Impalement attack bonus +?.
