Doesnt seem long enough to me and I am thinking that is for an auto flex plate. Summit shows them with a small shoulder, but doesnt give a length and they look just like the 1/2 long ones at NAPA. Thanks, Doc. I used to care but....... things have changed

The ones I have here have 7/8" of thread. Last aftermarket ones I got were found under a Pontiac application, I believe, as we couldn't find anything Mopar for these in the (I believe) Mr. Gasket catalog. If memory serves, they should actually be 7/16NF...not 1/2". Hope that helps... 2 Demons...no, not my kids!

I've taken alot of flywheels out of mopar v8's but never needed to buy a set of bolts. Since I wont be installing them right away, just wanted to make certain I got the right ones. Thanks!
