After that, in addition to the 4 below and one above the trans mount, I have to add an additional 1/2" of shims!!

The whole tunnel or just under the transmission?

Just the trans portion.

Speedtech sells that T56 tunnel which can be installed with screws etc if you don’t want to be welding on your car.

Installed this on my '68 that has a SBC and T56, I did the cutout with the finished interior, so welding wasn't an option and used 3M panel epoxy. Pain in the ass...yes, wish I had a garage that wasn't built to barely fit a 1920's car.

I see first gen tunnels. Not second.

I went with the 4l60 because they said a 6l80 would definitely require mods. I would’ve much rather had the 6l80.

Sorry. I’m stuck in first gen mode. It can likely be adapted to fit a second gen.

The reason I went with the 4l60 is because Speedtech said with that trans, I would not need to modify the tunnel like I would with the 6l80 that I preferred.

I was willing to go with that trans to avoid any tunnel work.

A CV driveshaft isn't recommended by two different shops I asked to hopefully avoid the angle issue. Both said the weight would cause transmission damage due to this.

Did you ever figure this out?
