Exhaust Bolts to Manifold

[Emtmike]

I'm changing my entire exhaust system on my '81 coupe, and need some help with the bolts that hold the system to the manifold :confused. Mine are sort of rusted since it's the original system and I will try not to break them if I don't have to hnoes. I also sprayed them heavy with Liquid Wrench to help break them free. I was wondering if these 6 bolts are compression bolts since the top seemed flat. Let me know if these can be bought, and where.

Those are nuts (on studs), not bolts; they're prevailing-torque crimped nuts. Paragon has them, #6498K.

Thanks JohnZ,

I was able to get the nuts of with alittle pressure and going back and forth with the rachet hnoes. I'll replace them if need be, but for now, I'm almost done with the installation
