Have I found a 4x4 Shortbox Highlander?

[davepl]

I'm looking at a 72 4x4 that has the blue plaid interior. On the SPID, I see:

148210 WHITE/DK BLUE/WHITE
161010 BLUE CLOTH CUSTOM T

Other options of note: AC, locking hubs, 3.73 gears w/POSI, Tach, Super Cport Cheyenne, PS, PB, tinted glass

A couple I don't know what they mean:

K5 "Manual Throttle"
F5 "Front and Rear Shoc"

It needs work, but the bigger questions are (1) "Is it a Highlander" and (2) "Is a 4x4 Shortbox Highlander a 'Big Deal'"? He's asking $4500, and it looks complete and restorable.
