Front towing D-rings. Cab11/12? Bolts securing bumper

[cletrac (RIP)]

To remove a broken bolt in cast iron I use a cutting torch. The bolt blows out without melting the cast then run a tap through to touch up the threads.

Grant, Rob, Dave, thanks for your suggestions to get the remains of the bolts out. I did try the weld method before the chassis went to the blasters, but I wasn't having much luck. I guess I tried 5 or 6 times, but every time the nut sheared of (or the angle iron I welded on at one time)...maybe I didn't get enough heat in the weld, I don't know...but after failing I cleaned up the remaining material and added a centrepoint in preparation for drilling the studs out.

Mike, that's exactly what I was after. I am surprised the bolts are just plain bolts as the parts book didn't mention a size, only a part number and description. Did you really remove one bolt just to answer my question?

Thanks for the imput guys. I hope to have ago at removing the studs this weekend.

Paul...Mike is right; I should have mentioned "Chevrolet".

I had the same problem, a couple of those bolts on my C8 were broken off . I drilled them out carefully .

BTW the early production C8 used a folded bumper bar , but later they were fitted with a channel iron section bar , the corners are sharper . The folded bumpers have rounded corners Mike

Hi guy's let me just say a broken bolt in whatever vehicle is a problem, we all have different ways to remove the bolt and if our combined knowledge helps that is the reason the forum is here. Well done to all who replied, did the bugger come out?
