new clutch line help

ok, while i was bodydropping my truck and i was welding on the firewall it burnt through my clutch line. i got the new one but now i'm trying to figure out how to get the old one off. it's a 4.3 5 spd in an s-10... the slave cylinder is a codler pin set-up, but when i went to pull the pin it was so rusted it broke. so how the hell do i get that thing out? can i drill it out or should i use a punch and try to just push it out somehow? it's really rusted in there pretty good so i'm not sure. but up on the master cylinder i noticed it's not a codler pin and it's actually just this little cylinder that slides into the hole, any ideas on how to get this out also? thanks for any help guys, i really wanna drive my damn truck sometime soon
