Slave cylinder bolts

Just bought a 2006 2.4 with manual transmission as my latest project. Had a hole in the block and engine was removed. I machined and rebuilt a core I had and was about to replace clutch and slave cylinder when I realized the slave has already been removed. So no bolts to replace it with. I am not against guessing and I have a bin of worthy candidates, but if someone happens to know what thread pitch and length I would love a hint or even a picture

That's the master. The slave actually fits over the imput shaft to transmission. GM discontinued them. Thanks for looking though

The actual slave cylinder (GM calls it the actuator) is not shown in that diagram.

You can see it as item #20 in the diagram at the link:

I replaced mine a few years ago when I replaced the clutch. I think there were 3 bolts. I don't remember the size unfortunately.

OOPS: this may be for LNF only, but you know the drill. Correct part number is 93368576 for m86 trans.

I am getting closer. These bolts are torqued to 89 LB. INCH. That info gives something to reverse engineer from.
And found the part number. at gmpartsgiant.com searching for clutch actuator bolt.
And then popped that into GoOgle and found a reference to M6X22, I could probably find the length, but then you would not have any fun left.

If the reference "M6x22" is correct then the bolt is an M6 (6mm diameter) that is 22mm long.

So it’s the thread pitch that’s missing. If you have a tap and die set you should have M8 1.25 or M8 1.00 taps to check the threads.
according to Saab site the tire bolts were used but hex is preferred for replacement

Thought I already replied with my thanks, evidently I did not. My local dealership couldn't provide me with the bolts. I harvested them from local junkyard. Finally got the engine back in and now I just need the stubborn slave cylinder to prime now. It refuses
