Hi guys, I am purchasing a SII PS box for my conversion into my 800. Came across a SII PS box with 4 mounting holes? I have never seen one with 4 holes before, only 3. Was this a thing IH did? It was a Lares box on rockauto.com. I have since found one I am going to get but was curious. Also, if anyone has reviews of PS gear from Rock auto let me know!
