The spacers were 1.5". The only problem I had with tire interference was inner sidewall to the frame rail. So with wide tires and no wheel spacers, yes I can see this being a limiting factor. It's gonna vary so much depending on your setup, so you'd probably just install some pivot blocks and then see what rubs first before you can make an informed decision as to what is needed exactly.
For me and the Tacoma housing, I was already running an 8" E-Locker, so I just found a E-Locker Taco housing and it was a very easy swap. I guess you could get an E-Locker housing and weld it up and rearrange a few studs to get a non-E-Locker 8" third to fit in place....?
I do like the BC Spring Rocker pivots because they have grease zerts which is a really nice feature:
