cracked clutch case 17a

Noticed some oil leaking from my clutch case.Now i know why there was fresh paint under the unit.Looks like someone over tightened the bolts or they were too long or maybe crap in the thread holes cracked the inner case.They had covered it with sealer and paint so my untrained eye missed it.Even the outer case has a small crack that isnt leaking yet.My question is this,is this repairable?I will post a picture tomorrow.I know cast doesnt weld very well and if its gotta come off it wold be nice to put on a good case.Does anyone know if there is a source for new or used components?Guess i was blinded by the fresh paint and new seat when i bought this ol girl.oh well.please help a newbie. thanks.😮:hurt:
