Diagnosis and Repair Bulletins (DRG's)
Many of these DRB's mention kits available from the factory to effect corrections or repairs. Since these kits are no longer available the information in the DRB's may give you some ideas on how to create your own kits or at least point out issues which may never have been corrected.
