Hey everybody, im on a couple days of vacation down in Austin/Round Rock/Hutto Area and I was finally installing my OS Giken twin disk Clutch.

When it came time to bolt up the clutch to the counterweight I realized I do not have the Bolts to bolt the flywheel to the counterweight!!!

If anyone, can be of ANY help at all please let me know! If you have the bolts for a reasonable price and you are local hit me up, if you know a source to buy high quality grade 8 bolts in the austin area please let me know,

And if anybody knows the exact size, thread pitch, and length of these bolts please help!

 

Call/Email Mazdatrix. That will at least get you the specs.

 

When I installed my OS Giken twin, they said to use the bolts from our ring rear. So I ordered some from my local dealer. The size is M10 x 1 but I don't know the length.

I have a bucket of bolts that I have saved over the years from working on my car and in it I found several just like the ones I bought, but I have no idea where they come from on the car. If you would like me to send a pic of the bolt, let me know.

And these bolts are a metric grade 12, which is stronger than SAE grade 8.
