Default how to varify a real 74 goat?

A friend of mine just purchased what was said to be an all original #'s matching 74 GTO, it does have the correct hood with functional shaker,and floor shift with console. Here is what concerns me, it has a 350 4bbl w/ th350 trans, 4 wheel manual drum brakes and manual steering,also it has a "custom" emblem on the sail panels, is this just a stripped goat or did they get taken???

I would say first thing to do is send in the $35.00 to PHS (Pontiac Historic Services) before someone buys a Pontiac. An extra $10.00 will get a fax back reply, quick.
This is first thing I do, and probably the best service for this hobby. Not many others have this service.

If not fimiliar with this service, this gentleman (Jim Mathison, an ex Pontiac employee) has the old files (up to certain year I think) for the dealer invoices and can verify the car and options by the VIN.

He can either fax back in day or so or send in mail an actual copy of the dealer invoice (broadcast sheet)
Plus you get a packet of interesting info on the PONTIAC model like production numbers, and many other neat items.
You can find him online at www.phs-online.com

I have used this service for maybe a dozen cars over the years.
Other than that I dont know much about the 74's so perhaps others can speculate what your friend has bought.

Here is some information to get you started on checking to see if the car is a real '74 GTO.On a side note....numbers can be changed,VIN tags can be swapped and others things can be masked to decieve potentional buyers so you need to check as many items as possible on the car to verify its authenticity!

1974 GTO FACTS
The GTO option was no longer available on the intermediate LeMans in 1974,but on 2 Ventura models instead-a 2-door Notchback and a 2-door Hatchback Coupe.The GTO could be identified by a functional shaker hood scoop,similar to the unit found on the Firebird Trans Am,a GTO decal on the right side of the grill panel,GTO decal on the rear deck or hatch,and GTO decals on each front fender behind the wheel wells.Decal color varied with body-color paint.In the interior there was a GTO emblem on each door panel.

Only 1 engine was available...a 350 cubic Inch V8 rated at 200 Horse Power mated to a 3-speed manual transmission.Compression ratio was 7.6:1., A 4-speed manual and the 3-speed automatic transmissions were optional.Dual exhaust were standard using a single transverse muffler.The stock exhaust tailpipes exited behind the rear wheels with chrome exhaust splitters optional.

A split bench seat was standard on the GTO,with a variety of bench seat variations and bucket seats optional.

Standard on the GTO were 14 X 6 RAlly II wheels without trim rings,which were optional.E70X14 belted blackwalls were standard.

Also standard were Drum Brakes, a .812 front sway bar and a .562 rear anti-sway bar.

All other Ventura options were available in conjunction with the GTO option package.
