I have a McSorley +4 chassis which has the rorty rear end for irs i need some advice on how to complete front suspension eg, which wishbones to use and whether anybody makes rorty rear suspension arms or ideas what to do?

I used the plans from the tiger avon book with no problems. Not sure where the U bracket positions are on the rorty plans, but if you're using sierra running gear then those kind of dictate the width.

do you have tiger avon plans as pdf?

Nah sorry I bought the book, and sold it a while ago.
