Az6 transmission adapter for a gen 3 LS?
 

I’m trying to mount an AZ6 transmission to a 4.8 engine out of an 05 suburban. I currently have a m526 in my 93 miata, and it won’t hold the power the 4.8 is making. I’ve looked online for a bit and I cannot find any adapter someone has made for these to bolt up. Does anyone know if this combo has been done, or do I need to custom fab myself?
