Rear Seat, bolt holes and gas tank

[miket]

Hey guys,

I am in the process of replacing my rear stock tank and noticed it had two holes punched in the top in the middle of each dimple. It looks like someone put bolts in from the top, where the rear seat sits that were too long and it punched holes. However, in looking at the rear seat that came with my Bronco (which appears to be original) the bolt pattern does not match up with the hole pattern in the floor and where the dimples in the tank are. so what goes there?

A previous owner might have installed something under the rear seat, such as a storage drawer or amp, and drilled into the tank by accident. When the body shop took off my tub, they found three holes in the top of the tank...

I thought of that, but the holes in the tub are threaded...like factory...like the seat bolt holes. That threw me.

Could it be the seat belt holes?

have my tub of the frame now, found lots of mystery holes, in 40 years and multiple P.O.'s you never know what you can find, I have looked at a couple of pretty original ones/survivor to get clues on what should and shouldn't be there, I'm not doing an original restoration but while I have it apart and prior to paint I want to fix anything I can, if you have anyone near you with original or there is a show coming up grab your camera, helped me a bunch as this is my first EB so I don't know what I'm supposed to see in some areas

Yep! its not from the seat but from the seat belts where they bolt in behind the seat, seen this happen before.

You're lucky. My seat mounting and seat belt mounting holes are missing the threads. Thus 2 people required to uninstall and re-install.
