The Muppet Show 25 years - Figure Stands Question

[MK Muppet]

I was wondering if there was a quick online resource which tells me which stands goes with what figures from Series 1 and 2? I pieced my collection thought many eBay loose figure sales, so I am not sure if I have all the correct stands. Kermit and Piggy have pegs closer together, but aside from that, who knows? I do see there is a tiny number on the back of the stands. Does this signify anything? Can anyone help? Thanks.
