Re: 67-72 Suburban OE seats

So both my rear seats are 50” seats. I looked SPID and it just says rear seat option. But if the weld nuts are factory placement then it goes in the middle. The rear plywood is not drilled for the 3rd seat. The rear seat I have also had 70-72 upholstery. Maybe they were swap out at the dealer when the gas tank went in???

Was your Burban a three row truck from the factory? It should be indicated on the SPID. The welded nuts on the crossmember reflect what seat layout the truck was ordered with. As far as I know GM didn't install crossmembers with weld nuts for both seat configurations.

Does your 3rd row seat have the factory style crossmember?

I believe the under seat aux tank was a dealer installed item only. So there would be variations in how they were installed. That being said I don't believe anyone has ever documented how those tanks were installed.
