You could have been a multimillionaire with your tremendous luck, but no, not you, you had to use it all up in getting a broken ezyout removed. If you ever get one stuck and broken, get the grinder and stock up on grinder point stones.

It will be touchy I admit, too bad the broken bolt wasn't a bigger diameter.
This method has worked for me in the past on other cars. It's particularly effective when the remaining bit of the offending bolt is above the surface. If the remaining bit of the bolt is above the surface, sometimes you don't even need to drill - just heat it up and weld it to another bolt. A squirt of penetrating oil afterwards has been useful too.

tried getting a tap extension today

I can't get the t-handle in there

all the ones I found were for a 7mm or smaller tap

a square drive would work

a friend lent me a tap handle with a sliding handle

it's working

taking it easy so I don't break the tap

got it about 1/2 done

I'll finish it tomorrow.

some of the bolt's still in there.

I'm hoping at this stage that it's friction welded in.

Prayers said that you have enough thread to torque the bolt down!
What a tough job. On my 87, the bolt on one rear shock wouldn't turn, rust welded shut. We used a grinding cutoff wheel to cut the bolt through and hitting the bolt and rocking torque, it finally came out. Then the nut and 1/2 the bolt on the other side we rocked torque while I beat on the center of the bolt until it finally came out. All evening job. the replacement bolt, just like any other bolt I reinstall got antiseize applied to it. I feel for you!
