You should not have to mess with the converter bolt holes on a "4L80E" flexplate

That has the flexplate, spacer, and bolts. All you will have to do is do a little grinding with a die grinder on the new flexplate to match you converter. The bolt holes are close but you have to open them up a little. Working fine on my LQ9/th400 and you won't beat the price!!!

Is that what you got from GM parts direct? If so, Its wrong, Looks like a 4L60E flexplate. It should look like this, Notice the 6 converter bolt holes.

I was wrong, You do have to open up the holes a little, I dont know why GM would change that on the 4L80E from the early ones.

The 6 bolt converter for the 6.2 matched the holes perfect.

That was a flexplate I had laying around just to see how far the holes were off. I used the one in the kit. The one in the pic will work as it was a dished plate as well but I did not have the spacer.
