4r70w adapter kit for bw1354
 

Not sure if this is the best forum to put this in, but given it's for a v8 we'll give it a shot. Anyways, my 5.0 swap is almost finished but im running into an issue with some drivetrain issues. They say advanced adapters makes a kit that will extend the tail housing of an aod or aode transmission to fit the bw1354. The problem is that I can't seem to find it on the internet. Did they discontinue it or am I going insane?
