Right now i have a 1996 4L60e(at least i think it is the sticker reads ID # 6KCD) with its converter also a 2000 6.0L with the stock flex plate to a 4L80e.

Well I read on some old thread that there are issues with bolting up Pre 2001 6.0's to 4L60e transmission's.

Heres the thread:
1999-2000 LQ4 6.0 Engine Fitment 4l60E - LS1TECH

I posted a thread there but i thought id do it here too.
My question is there some Flexplate/converter combo i can use to mate them up?

Here are some pics in case it helps:

So I went ahead and took Pics of the fitment Issues.

Looks like the 4L60e converter will not bolt up to the 6.0 flexplate. the converter bulge does not allow it to get the hole mounts flush with flexplate as seen on the Third Picture.

Anybody have any suggestions.
