Bolt specs for rear shock absorber, lower.

So, I managed to strip the damn nut trying to get it off, so I'm gonna got to the hardware store to buy new ones. Is there an exact size available...??

Gotta put the tire back on so I won't really have the old one to compare it to.

Thanks.

Guessing this is the right bolt..??

Thanks

Also, somebody mentioned I may have something called "nivomats" on the back, but every site I check gives me the same type of shocks I just picked. What's the deal with this...??
Thanks.
