Well thanks to a few tips (thanks to morpheus1977 and Gillmore for sudjesting the local Petsmart) I found a mohair girth in a good length. I am going to mod the length just a tad but that should be easy enough to do. I only need to shave off an inch on each side.
Belive it or not it only costs $7.99 to get the correct type of mohair girth... allthough they may have rung it up wrong becase it didnt have a tag and a lady had to go back and find something similar that did. I can tell its not a sinth becase it makes me itch like mad when it touches my skin. I am alergic to mohair.
After trying it on with my ammo belt, cod and vest I think my calculation to have the vest sewn long was an error. To look correct I had to fold the vest under an inch. But thats an easy fix as well.
I attached a pic to get yalls opinion on the adjustment on the vestola!
