Question for 4L80E to 6ltr

Alright I just went to mount the 4L80E auto to my 6ltr & the toque converter mounts dont line up with the drive plate on the back of the L98 just over half a hole out ??
What have people done to solve this problem ?? have you just change the torque converter & if so what one did you use ??
Thanks in advance
Cheers Dan

the depth is incorrect too.
new flex plate is cheapest option.

There is a specific Flexplate to suit. TCI and scat make them have a look at Rocket industries, or summit racing online

Have you got the Transfer case adapter yet and checked front drive shaft clearance? I put the 4L65E in mine and it was marginal it best!!
