See step 6 of the assembly instructions for the WCP SS West Coast Drive gearbox. Any configuration of sprockets, pulleys, and spacers can be used so long as it adds up to 2.25" and the chain/belts do not rub on the gears or face plates. The provided illustration shows two single sprockets being used in a fashion that allows the inboard chain run a little more space away from the 2nd stage of reduction. I believe this is the assembly method that 1712 used in 2016 for our drivetrain since it facilitated better chain runs elsewhere in our drivetrain (pushing the inboard chain slightly outboard gave us a tiny bit more bellypan real estate).
