I have located all the parts for the conversion, execpt the brackets. I will check runout, but I don't think there will be a problem. I'm using a MC from a 1990 4Runner (1" bore).

Isn't it the little things that make any type of conversion fun/interesting to do? If you could just buy something and have it work/fit the first time you bolt it on your truck, that would be kinda boring. Just my opinion.
