It'll work with the proper Convetor but it'll sit shorter than the 4L60E that needs to be in that car so there will be a Driveshaft issue.

I'd get the one that belongs in that car.

That's what I told him. He mentioned something about a spacer for the converter. He said everything else should be ok according to the tranny guy he spoke with

Get a crank spacer. Open up the stock LS flex plate holes to match bolt pad of the original 4.3 converter. And it should work. Some 4.3 4l60e already had a LS style converter and 300mm input shaft. Easy way to tell is remove the converter and look at input shaft.

It will be either a 298mm or 300mm tht will help with how to move around

Tailhousing you can swap out. That smaller V6 Bellhousing is shorter by a little bit if I remember right.
