I don't think the bike is worth investing in a Phill Wood BB, so, I'm leaning toward a Shimano cartridge UN55. However, the dilema is I only see 68x118 and 68x122.5 and the way I have the current chainline set is indicating I need a 120mm. So, do I order a 118 and use a shim.. or take the chance on a 122.5? Current setup, I have 2mm clearance between small chainring and the stay.

Also, I don't know how much the placement of the crank will change due to the taper of a UN55 (or whatever bb I purchase). I'm leaning toward the 122.5mm and hope it doesn't move the chainline out too much.
Roller bearings can tolerate a little play much better than ball bearings. Maybe consider reassembly with good grease and riding.
