Nothin special on the other side. Its just the bolts sticking out that will push agenst the bearing caps. After looking at the housing, I cant really see a point in tying into the cap bolts. I think most people are breaking the caps after the bolts are solved. This will also help with the case spread when using grade 10 bolts.
Why not just go with spacer plate, that has the holes tapped for the bearing cap support? It looks good though. I also not sure if the bolt on the passenger side or not.
