Driveshaft tunnel project

[67-ls1]

I’m in the middle of a project to enlarge my driveshaft tunnel because my driveshaft was rubbing the floor.
My car is low but not that low. But I set my engine/trans up a little higher in the chassis because they both have big, deep pans.
I had already enlarged the trans section so this really pissed me off that I missed this detail earlier.
Here are a few pics...

Lot of work there, turned out pretty good.

Thanks. I’m kinda stalled right now because I’m electrifying a pedal car for my grandson.
Priorities.

Finally getting back to it.
Started bending up the tunnel sheetmetal, starting at the trans tunnel and working back.
Mostly tacked in to the front of the back seat.

Back on the project and close to finishing.
Driveshaft is back in.
Added Dynamat to the new tunnel
With the increased height of the new tunnel the carpet no longer reaches the door sills.
I cut the carpet up the middle and started at the sills and worked my way to the center. This way the seat and seat belt holes in the carpet fit again. I’ll have a separate piece made to cover the tunnel where the console doesn’t cover it.

All buttoned up....

I am a novice fabricator, trying to mod the trans tunnel If I could trouble you with some questions.
What material did you use to raise the floor brace?
Are those hoops in the pics just attached to the floor sheet metal?

[67-ls1]

I’m a novice too. The hoops are 1/8” steel and are shoved down into and welded to the ends of the original floor reinforcement brackets that I cut out. I’m not sure if welding to the sheetmetal floor would be strong enough.

Thanks for the help, that makes sense and is with in my skill set.
