pics of my wilwood disc brake conversion

This sound like a great priced conversion better than most.
I did check Wilwoods site.
They recommend 15in wheels.
I don't know if the bolt pattern they list is a misprint but they say
4.50in. and 4.75in. it sure doesn't seem right mine are 4in. I believe.
They say it may change the wheel offset also.
Hows the offset on yours did it change much.
