CZ Mr. Fly in Manners VPT?

Should be any stock with factory inletting. Djdillondon had to enlarge the trigger area of a Bodys tacticool and I sent a chassis back to MPA to have it enlarged. Fly trigger and I believe a Timney require additional inletting
 
Looking at the fly trigger on cz's store page it says fits cz 455 with serial# greater then A956497. I have a VPT with serial# starting with C and have a Bscar trigger arriving soon. I hope it drops right in.
