Need help with 835 recoil pad

[Borden811]

Hey guys. Recently ran across a gun I've been looking for forever. Found one of the OG mossberg 835s with the 24" barrel, skinny round ribbed forearm, and the realtree brown leaf camo. Does anyone have any idea what aftermarket recoil pad fits it(preferably a Simms of some variety). I bought the one listed for the 835 on Simms website, but the holes don't line up, and the pad itself is quite a bit larger than the stock. I'm guessing the early synthetic stocks were a smaller size than the current 835s. Anyone have any experience with this, or any helpful info?

Did you by chance get this gun at Elk County ammo?

No sir. Grice.
