Driveshaft problem??
PY Family……1969 GTO…. 468 with 200r4, driveshaft made by local shop. At first years ago I noticed a circle around the driveshaft, thought it was hitting the X-pipe, muffler shop said it was not. Now there are marks (circles) in at least 7 spots, each circling the shaft…….I don’t see any obvious spots on the undercarriage where it could be making contact… wth…… any ideas… ? I have add coil overs in recent years ….thx
