[Old Makita parts resources]

Looking for resources for old and discontinued Makita parts.  I have a 33 year old 2030N planer that needs a few parts that aren't available through Makita anymore.  Any help would be much appreciated. Thanks, Steve

[Makita 2030N]

By beloved Makita 2030N plane / joiner broke the torsion spring in the roller drive chain assembly....problem is Makita has discontinued this part and it is now listed as obsolete.  Any possible avenues to find someone with this part in stock?  Makita USA was no help at all.  Thanks, Steve
