Hi from Downunder

[chook]

Well, actually born and bred in New Zealand, but have been living in Australia for the past 20 years.
I have just recently purchased a 1971 Cheyenne Super C10 Truck,
SWB Stepside, 402BB, TH400, 4 season A/C, ps, pb, push button radio, tilt column, tinted glass, woodgrain finish, houndstooth cloth upholstery, Hugger Orange,etc etc, a fully loaded truck.
The truck was imported as a stepside some 20 or so years ago by a previous owner. The last owner and his son have been restoring the truck back to pristine condition for the past 10 years. It hasn't been on a road for this time.
I was lucky eneogh to stumble on it by chance.
I have a question for all you learned folk out there.
I don't know if this truck started life as a Stepside or Fleetside and I was hoping someone out there could help me to solve my dilema.
The VIN#CE141S666404 tells me that it is indeed a Stepside bed. However the glovebox label tells me different - Model#CE10934, Fleetside bed? and a host of options that are on the truck. Am I reading this correctly or am I missing something?
Did GM produce Cheyenne Super Stepside beds in 1971?
I can't find much information on it, only what I have read in US magazines.
If it is an original Stepside then I have a fairly rare truck.
Any info would be appreciated.
Thankyou and Regards
Chook
Also I am having difficulty attaching jpg files as they are too big.
How do I reduce the file/photo size to enable me to attach pictures of the truck?
