Default DM Flywheel Specs?

I have been searching for a DM flywheel replacement for my 1994 Coupe, 6 speed. I have come across 2. One guy said it speced out perfect (came out of a car with 50K) the other guy said his looked good. My question is what specs are they referring to on a used Flywheel, what do I need to be looking for? Also, are the flywheels the same for all LT1s w/6 speeds or are there fitment issues between the different years?

You're probably referring to the amount of force necessary to rotate the plates. Should be posted in a 4sale thread -- if you go looking. Seems like it was somewhere in the 15-30lb range. But I don't remember.

The DMF has to be bolted down to perform the test.

There's also thickness but you'd probably be fine with anything having less than 100k miles.

Seals on the newer DMF are considered somewhat more reliable as the seal was redesigned after the first two model years.

All DMFs are the same regardless of model year...though I think the splines are different for the Z cars.
