Wilwoods from a 9" on an 8 3/4"

[Gtrpunk23]

My dads got a set of good wilwoods he isn't using on his 9" and I'd like to reuse them on my 8 3/4". What does it take to get this to work? Is it just a bracket swap? Any help would be great thanks.

It could be as easy as calling up Wilwood and get tingthe correct 8.75" brackets.

But I guess it would depend on the calipers and the specific mounting offset (if there is any difference between the requirements from the 9" to the 8.75".)
