It is not like selling a bow. I do not see why any Mathews dealer could not buy the bushing pack, (there are only two A+B packs) and they will have all the bushings needed for your bow. Retail about & to 10 Bucks + shipping and you will have it.
If all else fails PM me and I will go to one of our dealers and buy it and ship it to you. Just be sure to give me all you bow specs so I get the right bushing packet for your bow. If you have the exact thickness of the bushing you need, I can check to see if I have an extra for one of my old bow’s. That I would just send in a letter at no cost.
