It may also be worth looking at the Kato assy parts range, given they've offered 20 Series stock in 1:80 scale. Failing that, have you tried gluing the broken parts? Gel superglue with "powerflex" is pretty effective, even more so if there's space to hide a bit of thin brass strip reinforcement behind the side frame without it jamming the wheelset.
