Hey! First time poster but ive been on for a bit. I got an RTS frame and shock for $50 and built it up with stuff i had around, only to realize that the chainstay is cracked in a few spots where it pivots and meets the seatstay. the frame is 6061 t6, serial num below. I can find every part online but chainstays. anyone know where to source one/if they are repairable? seems like a hard place to weld. ill post pics of the cracks later.
