    92451LS is rated 4.0 out of 5 by 2.
    Rated 3 out of 5 by from Poor instructions The housing looks well built, but the instructions were terrible. They said to cut the old housing off, but not to touch anything on the pan deck. I followed the instructions, and the 20ft-lb specified torque cracked new housing because the edge of the pan deck interfered with the bottom of the housing by a few thousandths of an inch. Unfortunately I haven't seen any other brand that makes these for an LS, so if you need one, this is about your only choice (at the time of this review)

    Does this require a dished flex plate or a flat one to mount a TH400 to an LS1?

    Asked by: Eltrap
    You can use either one, if you use the flat flexplate you will also need the spacer.
