i have an 89 iroc v8 im replacing the gas lines under the car i got original lines from gm and im wondering if you guys can give me some tips on putting them in.Now the problem is one of the crossmember bolts snaped and im trying to just run the gas lines over the crossmember but thats not working to good.should i drill the bolts out?a few buddies of mine said that a sh*tty process. any tips on how you guys have got passed this problem would be much help.

 

i'd weld a nut on the broke bolt and then use a wrench on it, repete as needed

 

I had a bolt head snap off on my crossmember too. That's where I decided to quit. Is there a solution to this? It would take days to drill out all four bolts.
How in the world would you weld onto the broken bolt without welding the crossmember/subframe?
