1986 Husqvarna WR400 conversion

[Little Panic]

I'm getting ready to recreate what Tricky Dick did with the 1986 Husqvarna CR250 but I'm doing it to a 1986 Husqvarna WR400. I've done a lot of internet research on his Cagiva's and saw a recent posting by his son. I'm stuck on what was used for the rear carrier assembly and the rear master cylinders that were used. Was the rear carrier assembly, and axle from a Banschee?, and where did the rear master cylinder come from on the Cagiva's and the lone Husqvarna?
