I went the hard way and measured the depth of the holes, went to ACE and got some rust free bolts to match thread and depth, and then incorporated flat washers and lock washers.

Really it wasn't that hard, since KAs have almost the same thread pitch in every hole, I just took an engine-to-tranny bolt for thread pitch matching, verified the depth with my calipers, and spent about 6 bucks for the stuff.

I like this setup better cause you get the lock washers to ensure that it won't come loose. I NEVER put loc-tite on tranny bolts.....the possible nightmares of bolt removal keep me from doing it.

Oh for something as special as that, i'd never put random bolts in, Pun has the best idea, get the proper oem bolts for it! Good Luck. I have learned that every bolt on an engine is special, if you use something other than what is intended to go in the hole, damage can occur like stripped threads and those are the worst problems to run into. Always use the right stuff, that's my 2c! Good luck with everything.

Well the only thing "special" about them is the bolt rating. IIRC Nissan uses "7" rated bolts for most things. All this really means is the holding strength of the bolts. Only going softer can risk breaking bolts. I have never heard of someone breaking off a tranny, pressure plate, flywheel bolt. You would have to deliberately mishandle the bolts to damage them.

Mainly because the pressure palte bolts only call for 16-22 ft lbs, IIRC. Torque to 20 and you're good. With only 22 ft lbs. for a max torque spec, the bolts aren't going to be THAT hard.

Save some money and just go to your local hardware store. Nissan charges like 1-2 bucks per bolt....x6 = alot of money for just bolts. AND they have to order them 99% of the time...which = wait times. I hate wait times.

edit: found the page in the FSM, go to: GI-39 for the bolt reference. Sorry I would post it up but I don't have the right image scanner on my work computer.
