Flywheel questions...

I bought all new stuff back in '05-'06 for when I was going to go 5.7 / TKO500. I bought the '05 Ram 2500 bell and flywheel with Saches clutch / pressure plate. Both the bell and the flywheel were only about 60 bucks back then. You should try OEM new, you might be surprised.

Also, the bell was drilled for the Ram transmission (whatever that was) but there were additional bosses already there that just needed to be drilled and tapped for the Tremec and possibly others. I was real surprised about that.

Unfortunately, as my post above yours concluded, I can't really make use of the stock flywheel. I have found this however, which isn't cheap but it's at least not outrageous like many of them seem to be advertised at. Sucks though that it uses a 11" clutch unlike the original 3.9L flywheel that had an 11" flywheel designed to use a 10.5" clutch which are much more common and lighter.
