Grade 5 or grade 8 bolts from pressure plate to flywheel?

[bull]

Just wondering if this is a spot where grade 8 bolts are a good idea? And I assume it just gets bolts and lock washers, right? How about a little Locktite too?

Yes. I believe that grade 8's are the norm. You need a minimum of 150,000 psi tensile strength to call it Grade 8. These are 170,000 psi bolts. http://www.jegs.com/i/ARP/070/147-2201/10002/-1?CT=999  Loctite is always a good idea.

Mopar 10mm X 1.50? What?

Those were only an example of Grade 8 bolts. Do you need the exact bolts and where to buy them?

Oh, ok. I was actually looking at these: http://www.megapartsusa.com/proddetail.asp?prod=110%2DC8207

Those look good. From the linked table http://www.portlandbolt.com/technicalinformation/bolt-torque-chart.html those 3/8's bolts at a torque of 30 ft-lbs look to be grade 5. What you are buying are most likely that grade (not that there is anything wrong with that   ). As far as using loctite, I think if you torque the bolts properly there is really no chance of them backing out; the loctite would really be superfluous.

  Now all I gotta do is wait for them to arrive.

You ordered hardware specifically intended for flywheel and pressure plate? I hope so.

I install mine at the higher Hemi torque specs since the hardware is the same.

Ah, here-http://www.mymopar.com/torquespecs.htm

55 for RB, 70 for Hemi, both with 7/16-20 size fasteners. I don't see pressure plate torque in there but IIRC it's 35 B and 50 Hemi.

That's what it says in that link I posted. I can call them for the specs today to make sure but they're saying they are pressure plate bolts.  http://www.megapartsusa.com/proddetail.asp?prod=110%2DC8207
