Gun Talk Vepr FM-AK47-11 folding trunnion rivets

OK... I'm new here but have a decent presence on the marketplace forum. I recently bought a Vepr FM-AK47-11. I also bought the Molot folding stock and folding trunnion that is native to it's sibling.... The FM-AK47-21. However, some drilling is requires to convert it to the AK47-21. I know it's a thicker receiver... 1.5 vs 1 mm. Question, what rivets would work? I'm looking at the AKS-74 folding trunnion rivet set but not sure if the receiver thickness will factor into rivet length. Any help is greatly appreciated.
