35wssm dies

looking for the least costly way of getting a set of dies for a 35wssm. not looking to change any case deminsions except the neck size. can a set of 25wssm dies be modified to .35? can you just change the neck sizing collet in a die set or will they have to be custom made and if so by who? thanks for the help. i have been reloading for 25 years but wildcatting is all new to me.

I used a collet die set for my .30 WSSM. It worked OK for the few rounds I loaded. I would suppose it would work for a .35 as well.
