Im doing the swap right now actually and last night I went to go and mount my tranny and my worst nightmare came true, my motor was about 1.5" to far forward.

When I was looking at what designs of plates were best I could not find ANYWHERE that said "this one is stock location" . I finally stumbled across an obs swap and he used the S&P design plate so I figured well he did , so can I .

My truck has an nv3500 5 spd in it ... you can understand why I REALLY did not want to move my transmission .. my shifter would move.

So my suggestion is use the S&P design plate a picture of it is here ( LS1 Swap FAQs - LS1TECH ) and move the engine 1.5" backward of this.

Good luck

You also have to make sure that you put the plates on the correct side of the motor or it will move it too far forward, learned this the hard way.
