    Rated 5 out of 5 by from If you are running anything with a lot of horsepower this is a great part to use definitely thicker and just touch heavier than stock but well worth the money for the safety side of things

    Rated 5 out of 5 by from LS to t400 11.5" bolt circle converter OR 4l80e I ordered the 399753 first, as its listed to work with an LS to an early transmission and converter and includes the snout extension. Unfortunately it had the 10" and 10.75" circles, and not the 11.5" I needed. JEGS super easy return process had the new one on its way before I shipped the one in my hands back. Well built, great looking product, I wish descriptions had a little more info but that should be on TCI. This thing is too pretty to have hidden inside a bell housing.

    I am putting a 2004 5.3L LS motor with a 1994 4L80E transmission in my 1951 Chevy 2d Sedan. Is the correct flexplate?
