Front Leaf Length Question

[88_YotaCrawler_88]

I bought an 88 pickup that was built up but im trying to change the front leaf setup because its trash.... Pretty new so I don't know where to look for leafs. They are 47 eye to eye, 20 from front of leaf to center pin and 27 from shackle to center pin, kinda weird.
So my question is if I go to a 47-22-25 is it going to mess anything up? Thanks, I can post picks in a minute, any help is much appreciated
