I have a spare rag joint assembly from my '75 Ranchero which I will rebuild with a never fail rag (fiber reinforced rubber). I'm not sure what all years this fits - I'm thinking '72 - '79. This is free to you provided you send me your bad assembly and pay the two way shipping - mine to you and yours back to me. Send me a PM if you want this.
So I rebuilt this spare rag joint if you need one. Same conditions - free to you provided you send me your bad assembly and pay the two way shipping - mine to you and yours back to me.
