I have 72 blazer and putting a lq9 w/4l60 out of a denali. My question is if any body has put that 6.0/4l60 with older transfercase if so which one. thanks

 

I put an LT1 with a 4L60E into a jeep with a Dana 300 transfer case. Pretty much the same thing you are trying to do. Look at advanced adapters, they have adapters to put pretty much anthing together. That is if it won't bolt up properly.
