From Bob:

So I have the offset trailing arm. You have to mount it for clearance on the inside of both mount points, then shim the outer part. I got away with about an 1/8 inch spacer so it had good room to rotate if needed.

The wheel I used is an Enkei Kojin 18X9.5 +45 5x100. I have ARP studs, and had to use 2 10mm spacers to get it back out off the trailing arm, but still under the wheel well. The tire is actually a 285/30ZR18 Hoosier A6.
