Help with 914 for sale on eBay, Real 2.0 Liter??????? Options

[2pointOH]

Clubbers--

Got a friend who is interested in jumping into the teener market and needed some help on a car he saw on eBay. For sale in York, PA. Auction din't close late last week. Owner says it is a '73 2.0 liter but we're having trouble authenticating an engine code (GA for 73 2.0 liters correct?). Auction ended just over $3K. Owner is looking for $7,500.

Couple of Q's we have:
1) is this a real 2.0 liter?
2) is this a factory or custom interior (we look to change it)?
3) other problems to look for (engine bar, floor boards, undercarriage??)
4) where do we find/confirm the engine code?

Here's the item number to look it up: 4650963224

Here's the link: http://cgi.ebay.com/ebaymotors/1973-Ivory-...1QQcmdZViewItem

Any advice or someone in the area that can check it out would be GREATLY appreciated.

THANKS!!!!!!!!
