Flexplate, Spacer & Bolts from a 6.0l/4L80E 2500 HD..

You will have to oval out the holes for the smaller convertor pattern on the TH350.

TH350 installed behind my 408 in my MCSS.
does it have to be from a 2500 hd or would a flex plate out of a workhorse truck with a 6.0 work......
Great work on the install
