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

I remember @chris foley @tangerine racing used to sell replacement threaded tubes for the specific condition.
Not sure if he still has some, but I looked on his website and did not see them.
Pretty simple, a hole saw top and bottom to remove the old ones and the weld in the new ones, which are a larger outer diameter
