I found out that while the Tahoes, Yukons have a different part number, the cross members off a Suburban or 4 door Tahoe / Yukon will work. They have an extra rivot on the top compared to the Tahoe. I just left the hole empty since there was no corresponding hole on the TAhoe
I still have not got the tank back on. I've been working on other stuff while I wait on a couple of parts.
The Fuel Tank Insulators for the Tahoe are GM part number 15705173 - the 2 foam strips that provide a cushion between the tank and the cross member It takes 2 Insulators. They come one in a package for about $5 each
