Tubs with stock frame rails

I am going to put tubs in instead of doing the mini-tubs, my very narrow Dana 60 forced me to get creative with the install. For those unaware the stock frame rails are 38 inches, my Dana is 41. So I had to go an additional 7/8 inboard and that was the most I could do to make everything weld in solid and I still had to trim my backing plates and assassin bars bottom plate (where u bolts go through) I put my axles in to get my wheel size figured out. I ended up buying 15×12 weld draglite with 2.5 inch backspace. So with a .5 inch spacer I'll be able to run the tire I'd like (29×12) which would fit in a mini-tub but Incase I need a bigger tire I'd like to have the room already.
Alright so who done it, can you show me some pictures so I can get an idea.
Thank you dudes
