I have a request for those that have a Chevy or GMC AD truck to send me a few pictures of your original firewall, the roof line at the upper windshield, side cowls and inside back panel and gas fill.
The reason is I wanted to add it to the FAQ here on how to identify a truck that's in pieces which is the way many of us buy trucks and parts. Most think all AD cabs are the same but they have subtle differences between years that can make it hard to swap panels and explains why new panels don't fit as we think they should. It would also help when your cutting old panels for reuse you will know what year not to get them from.
1. Pictures should be frontal view of the original firewall not a smoothed or plugged firewall without engine if possible and the year on the Vin tag, not reg year, It should show the entire firewall and all the holes.
2. The side cowls,
3. The area at the pinch weld on the roof windshield in the middle of one side or the other.
4. The gas fill area and which side its on if it has one.
5. The inside back panel, a side view is fine.
Id the truck by year of the vin so we get the production year not the state title year. Series IE.. 3100 , 3600, 3800 or higher. How many windows, Make, either GMC or Chevy
If you have pictures of the front fender side view from a big bolt series send that along with series and year or a side view of a complete big bolt that show fender hood and front of the cab. that would work as well.
Send them to
info@thoroco.com and as soon as I compile the information I'll post it up.
Thanks for your help in this.
