tank questions

[ccautoupholstery]

Hi I'm new to the site/first post so hi to all and thanks for any future help. I have a 67 c10 long bed that I'm about to put a 350 and AT and before I start it up I want to replace the stock tank and relocate to between the frame for obvious reasons but don't want to spend a few hundred. I was told that the tanks from the suburban and blazers are pretty much exact fit. Is this true? And if so which yrs/models would work?

I believe there is already a couple threads on this topic. Use the search function on this forum to find more on them. With that being said, I believe it was the 31 and 40 gallon tanks found in 73-87 suburbans and blazers. Blazers don't have 40's though
