First, let's establish what you're working on. If it is a midget, yes, it could have either 31 or 36 spline pieces, and they do not work together, if it's a mini-sprint, it could be lots of things, but most are either 27 spline, 1 3/4" axle, or 31 spline, 2" axle, and again, they don't work together, AT ALL!!! If it's either of the 2 machines, and has a 2" axle, I have new spacer kits in stock, I'm out of pressure plates at the moment. Look things over, and do some counting, you might just solve the issue very inexpensivly. Bob!
