Motor mount bolts

So the bolts that go from my motor mount to my engine block sheared off this weekend and I was wondering what grade book should I put in there I've had some old man tell me grade five is fine I'v also have people tell me I need grade 8 . I have also heard that grade eight is too hard and I need something between five and eight I have no idea where to go please help me fourm

Just go to the parts store and buy new mounts if your jeep is stock. Had this problem alot when I drove an 85 Dodge Ram.

Oh, gotcha, figured they'd have the hardware, but guess not, never changed jeep mounts. Guessing they don't sell the hardware separate either huh?

More info on the Jeep? year, motor ect?

I was just told by a credible source that grade 5 is fine as long as they're torque to the proper torque so that's what I'm going to do and hope for the best I'll let you know what happens. 1988 yj 4.2 I6

Brown Dog sells brackets that attach to the block using 7 bolts, if you keep on having problems. And they use grade 8 bolts.

I have their motor mounts, very good quality.

There are addition threaded holes on the block. the dogs are larger mounts on the block to utilize the additional mounting points
