Could I just throw on some washers and longer bolts for the trailing arm bracket drop? Or should I go get the read deal, or make some spacers from 2x1ish steel tubing.

 

Thanks-

Washers only will add some shear load.  I'd get a plate built to drop on top.

What do you mean by plate built to drop on top?

Grab a set of trailing arm mounts from a 96-99 outback. The geometry of them will also push the wheel back to center of the wheelwell.
