[67 C-10 LWB]

I am looking at purchasing an 83 GMC 1/2 ton short stepside 4x4. Here are the specs:
5.0L (is this a 305 or 307?)
PW/PL/PB
AC(Not sure if working or not)
Auto
Woodbed
after market cassette player
137,000 miles
It is in awesome shape, looks like it has been redone, few stone chips and a couple scratches from driven it, but I couldn't find any dents or bondo when I looked it over last night. It appears to be in stock condition except it has aftermarket A/R wheels. Its at the local car dealer, I haven't listened to it run or driven it yet, I will tonight after work, they are asking 6995 for it, is this too much? Seems a little high to me, but maybe I am wrong, what are your guy's opinions? Thanks in advance.
