Rear trailing arm broken bolts, How in trouble am I?? Options

[PaIsa]

Long story short, 2 of the 3 bolts holding the left rear trailing arm broke on me. One broke and left some of the bolt out of the hole so I thought I could get it with heat and vise grip but nope. She is stuck. The other one broke and what is left is in the hole.

I cannot believe I am the first 914 owner dealing with this.

As I said, for the bolt that left me something to work with my plan was to heat it and use vise grip to try to get it. Tried on multiple occasion but she does not want to come out.

For the other one I guess I only have left to dril it out and try to redo the threads hoping for the best.

Does anyone has any other advice or method to try.

I do not have a welding machine so welding a nut is not an option for now and not sure it would work (for the one that sticks out of the hole).

I am open for any advice. I plan to work on this with my son this weekend.

Thanks

Just to close the loop on this, here is how I finally got this sorted out.

I first removed the rear outside bobbin that had a bolt broken in it. After I removed it, I was not too confident that I would be able to properly sit the new bobbin I got so I got a new one machined. The new one I had made was 0.5 inch larger in diameter which gave me a better seat on the bottom of the console. With this new bobbin in hand and with the help of a friend of mine and his probably 50 years old stick welder, we got this new bobbin welded. The result is pretty good, as far as I am concerned. He was able to weld both top and bottom. To make sure it was in the good position, we used the L-shape part that goes in the trailing arm when he welded on top of the console. Here is the result.



Then for the other bobbin in which there was a broken bolt, I decided to drill through it and use the long bolt & nut method. I took my time to complete the drilling and finally got though. Here also, I used the L-shape part as a drilling guide and tried to stay as straight as possible



I then got everything back on the car and lowered it to the ground. The wheel seemed decently straight. Got the car out for a ride and it drove good. It did not behave weird. We have been driving it for close to a 100 miles now and still good.

I will keep a close watch on this to make sure it stays like this and as well I will get the car aligned as soon as I can bring it back to a shop I found that can do that for me.
