Measure the existing 8mm to get the correct shaft length and thread length for the 10mm bolt. If you can't find the correct shaft length and or thread length, just get the full threaded bolt. Those bad boys will never break again...

While you have cradle off, pull out the front engine bushings and grease them up.

Cheers. Pat

Thank you, Sir...  the stock bolts are M8 x 30mm x 1.25 thread pitch.

I do think I will look for an M10 that has 10mm of shoulder instead of all thread... the stock bolt has some shoulder and to me that seem right for this placement.

Get the overall length close, you can run a bit proud inside the frame, then run your die up the bolt (cut new threads)  so you get the proper shoulder (shaft) length.

Weird that Yamaha used 10mm holes in the frame rails huh?

Definitely weird...  But not as weird as you having seen 3 different late model FJ's with broken bolts... in that location. That is actually rather comforting to me because my mind is looking and and thinking about the rear suspension linkage that I just bolted up untested and with no engineering (shade tree wrenching all the way) as well as the dog bone failure....  either of which could have resulted in the kind of forces that would unintentionally stress that connection and sheer a bolt... 

But ok! It appears Yamaha shorted the engineering and an up-sized 10mm bolt sets me free!!
