Kevin, you are right on the money. No two Spyders are exactly alike, there are lots of variations in there. But I do believe the shifters are all pretty much offset to the right.
Even with my center-mounted shifter, the 2-3 and 3-4 shifts usually touch a passengers leg. There simply isn't much if any room there. It is much better when my small-framed lady is next to me though, compared to a 280 pound instructor LOL!
