Fork spring question

[tommymac]

i think the fork springs on my priller are prety much shot and am looking ot replace them. Several friends have recommended sonic springs. Now I contacted sonic directly to see if they have springs for the futura. They said they have springs for the falco, and I would look to see if theyre the same length. They are both 43mm showa forks. Now on the af1 microfiche thye have different part #s but then I looked on race techs site and mostof the aprilia's have the same series # including hte futura, falco, tuono and millie so I dont know if race tech just cuts them for the proper length.

I posted on the af1 forum but havent gotten any response, and figured there ar eplenty of knowledgable folks here who may be able to lend some info.
