srx/exciter secondary clutch's

[thunderjet440]

are secondary springs available for these clutch's yet? need to update the gpx clutch but i really don't want to be chasing around obselete springs,if not,do springs from any other brand,or aftermarket company match up well? i seem to remember someone running a polaris spring?? thanks

I put a Polaris 'red' spring in my Exciter secondary...works great
