On the transmission the dust cover is missing - if any one has a dust cover please send me a pm. The engine really leaks oil and the rear main seal will need to be addressed this winter. The paint shows more wear than you would like, but at the same time it looks pretty darn good for a 53K mile survivor. The drivers side window needs adjusted, and the sway bar end link bushings are totally missing. All in all - not too shabby. here's some pics.

Looking good & congrats again.
IMO & '78 T/A 6.6 W72 WS6 experience - note:
- the missing end link bushings were urethane from the factory for WS6. IIRC most ALL parts books will just show standard rubber end-link bushings which will work but without the urethanes the difference in handling is like night and day. A simple fix that dramatically increases suspension performance as designed by Herb Adams & Pontiac Engineering for WS6.
- the stamped subframe extension was installed as a heat shield for fuel lines from the OEM CatCon that was offset and positioned in the passenger footwell area.
- exhaust replacement is what you want it to be IMO. Personally both our T/A's have true dual w Dynomax Turbo style Muffs w factory Splitter tips. The '78 has a simple "H" pipe with factory manifolds...and ran 14:89 @ 95mph w closed shaker
