So I have a 2007 L92 and a 2005 4L80e with a stock 4L80e converter.

The L92 has a flexplate, do I need a 4L80e spacer?

I was thinking of buying a SFI flexplate but am confused on what will work.

I found a 4L80e TCI flexplate part # 399754 168 tooth.
The listing says for LS1, LS2, LS6 & LS7 all GM GEN III LS engines.

Are there any other 4L80e SFI flexplates?

So does this part work for my application?
Do I need to use the GM spacer?
When I get the correct converter how do I order it correctly?
Do I order a 4L80e converter with the 4L80e bolt pattern and the longer shaft?

Are all LS flexplates 168 tooth as I need a starter?

thanks

That'll work.
I'm not sure if you need to use the bushing. All of the converters we sell are custom built. In your case we supply a converter with the billet front cover set up for your L92.
You will be disappointed with the stock converter. It's big, heavy and has a very low stall. Robs lots of power and doesn't like to spin.
