Your OEM one should work, my 1998 Z28 had the SBC bolt pattern (for a regular TH400 converter) ... just needed 1/8" spacer on the converter.

TCI Or Reactor will work, so will a stock one. Might as well put a stronger flexplate in there while you are at it.

Is the Th400 and 4L60e TCI flexplate the same?

Where do you get the 1/8in spacer and does it go between the flywheel and crank? Thanks.

The 1/8" spacer goes in between the convert and flexplate. It keeps the converter mated to the pump so you don't kill the pump in the trans.

Hughes also makes these parts, that's what I use. Part # for their flexplate is HP40004. I don't have the part # for the spacer, but they do make one. You can buy TCI or Hughes stuff from Summit.
