Erblestock Mainframe replacement waist belt

Any ideas or suggestions to replace the waist belt on one of these packs. The factory one never broke in, I finally just took it off the pack.
Not sure what your mission is but I highly recommend ditching the Eberlestock. They don't handle weight well and will make a long trip miserable!! Exo Mtn Gear for the win. Stone Glacier would be number 2....just my .02
