Blown M7 primary

[WILLIS]

Just blew up my spider on my 2006 M7. I am looking for a used complete primary as a replacement. Mines got 4k miles on it. My question is will a primary from a 2005-2006 xfire or f-series work. I know the weights and spring is different, but a have a spring and cutlers adj. weights, so thats ok. I don't want to run the KK 8.25 clutch. Any imput would be appreciated, Thanks
