I used that steel flywheel from Moparts that you mentioned on my build. I think I ended up getting the flywheel bolts from a truck engine since the car bolts weren't long enough. My engine was technically from a Charger, but apparently they didn't make stick shifts in 06 since the bolts weren't near long enough. The truck bolts fit fine though. I found my flywheel on Ebay for $100 off of the Moparts price and they had the aluminum ones for $100 off too I think. I actually have the part numbers for the flywheel bolts running around here somewhere, I can try to dig them up for you.
