I used a TIGREz wicnh cradle as the basis for my old setup.
I cut the cradle so theat it fitted between the chassis raild.
I then had a metal place make me some right angle brackets out of 10mm steel
I then bolted / welded the brackets to the reasr of the winch cradle and bolted the bracke to the chassis rails using hight tensole bolts.
I then mount a alumin bar with slots for the wicnh.
i sandwich the bar between the farleigh and cradle
