Which other brand sled primarys can fit on a SRX PTO shaft such as pol/arctic/doo and just wondering if the taper on the SRX clutch can go on other brands of sleds suchs as the Ski-doo ZX chassis 700 engine 
these would be for a strictly drag racing sled

As far as I know all the brands use the same 30mm 1:10 taper on their primary's and I have seen threads on here where guys are using a Polaris primary on their sleds.I personally know of one guy around here that is using a Doo primary on his 600 V Max twin.
