For those of us who don't have a press, can an M12 long bolt and nut with some body washes be used to pull the new bearing into the hub?

In theory yes but I don't think something like M12x1.5 would pull it, you would need a 1mm pitch thread (like low gearing) and you would need a LOT of (just under 74mm) washers to stop them bending.

Or perhaps unistrut threaded bar and brackets. The old outer race can be used to push against the new bearing. A large jubilee clip to keep the races mated while the new bearing is pulled into the hub.

You would need to grind down the OD of the old outer a few thou so it does not get stuck. Remember there are some pretty large forces at play here, if you clip let go you could lose a digit. Before I bought my WWII era ex RAF press (it must be 80 years old and in perfect working order) I used to use tut big copper ammer and a wheel bearing race kit plus old bearings I collected on the vice but I broke vices and was sprayed with high carbon steel shrapnel a number of times... I used to have a season ticket for A&E, especially the eye department.
