Default Who carries a 4L80 converter for F-bodies

This may have been asked before (search isn't working), but does anyone make a converter that will allow me to bolt up my 4L80E to a LQ4 engine without the need for a spacer? The trans is out of a 1995 G20 Van if that means anything.

Mods will be a 6.0 truck engine with a Vortech setup, 3.42 rear gears; it's going in a Trans Am.

And how much am I looking at? Would I be better off (cheaper) with a regular 4L80 converter and a crank spacer?

Z'mnypit did an awesome write up on the 4L80e swap if you need any other info, here is the link. https://ls1tech.com/forums/automatic-transmission/699277-whats-needed-4l60e-4l80e-swap.html

As far as converters go, Precision Industries (Vigilante) and Yank are the only ones that make them I believe. I bought a used one with my 4L80e. It is LSx compatible and is made by Precision Industries (Vigilante). The only other company I know of who makes them is Yank. They are going to run a pretty penny as far as price goes if you buy them new. If I were you and were not in a hurry, watch the for sale section on here, ls1 and ls2.com and try to find someone selling a combo. You'll save a lot of money and can send it back to the original manufacturer of the converter for a restall and thorough checkup. I'm not sure about a 4L80e crank spacer/converter compared to the other alternative though, maybe someone else will chime in.
