You can buy thread gages, or the dealer should be able to tell you.

 

I checked the catalog today. No description on the bolt size.

 

is the bolt completely missing? or do you just need another one?? Only suggestion would be find the right diameter, then hit the hardware store and pick up a couple different lengths.

 

90% sure it's a reg ass 10mm metric...


suby only uses 10mm, 12, 15, 17, & 21mm

basically that's all you need to take apart an entire subaru


gotta love it
