Modifying a Lee collet die?

I'm looking for someone to modify a couple of Lee collet dies to size a shorter cartridge than the die was originally intended.
Anyone who can do this or has had it done will know what I'm talking about. I have neither the equipment or skills to do so.

Thanks in advance, John.

John, I had a fellow on this site convert a 6.5X55 swede LCD to 6.5X47L. I've since lost track of him. You might ask the same question @ accurate shooter under "Guns & gunsmithing". Good chance you'll find your man there :)

I believe Lee precision will also provide this service. You may want to call em up.

I've had it done by Lee Precision.
I had a .243 die that was just a snootch too long. I sent the dies and some brass with it.

Call them first.
