Argon 18 kryton frame. Bottle cage bolts ok the seat tube are completely seized. The bolt heads are also rounded out and they're those sort of flat/mushroom type so can't grip them with a vice or anything like that.
I've tried ez outs and got nowhere. Pilot hole is always too big or small and can't get the drill to the lower bolt anyway.
Can't cut into the bolt to get a flathed onto it. Trying to now maybe cut the bolt head off and push rivnut into frame but even that's not sttaighword.
Need some help here and asked a few places.
