Ok, so after some searching and guessing i mounted the cross member.
I hope that it is in correct place, but i thought i would show and tell, and hope that if it wrong someone will point it out
so as you can see in the pic, i have mounted it to where the old mounting brackets where for the LT77 and transfer case were.
I also had to make some modifications to the existing crossmember, as my floor mounting brackets extended down and in the way..
If you have any comments, or if this is wrong please let me know
