LQ4 in a 1971 Nova
For reference, I've attached pics of what Chicago TDP did. I basically cut all the way back and plan to weld the C plate to the back side. I've already filled the brace cross-section on either side as shown in the first picture.
But would only suggest that the plate extend all the way down the side of the tunnel for some over kill and some Subframe Connectors to tie it in all together.

I edited the photos to show what I've done. The first is my plan thus far. The area in red was removed. Area in green is the C-shaped piece of 1/8" steel I made to weld to the back side. I suppose I could do like Chicago TDP, though move the top plate back as in the second photo.
What about a roll cage since you already have most of the interior out? This would prevent any unwanted flex from the tunnel.

Not saying you should buy a $750 tranny x-member but more on the lines of making a drive shaft loop/chassis stiffener. Cut the floor pan from left to right and recess the driveshaft loop/stiffener and then weld it to the sub connectors, floor pans, and tunnel. This would tie everything together and look badass all at the same time.
Something like this:

[/IMG] I've heard the praises from the remote bleeder, maybe it's time to pull the trigger while the trans is going in. Does it stay attached to the trans, or do you have to install it whenever you bleed the system? And what length did you get?
Also, here's what I ended up with for the floor pan. It's just riveted in right now. I hope to install the trans to check fitment, tack the new hump in, remove trans, finish the weld and paint tonight. That's a 1/8" plate I bent and welded to the OE brace and floor pan. It turned out pretty well, especially for FCAW.
I also wanted to note that I modified my reverse lockout solenoid per this thread due to space restrictions. A quick rundown:
Here's the reverse lockout assembly. That entire left half is the solenoid... Unscrew it and discard.

Next, the plunger is held in the housing by a snap ring. Remove it to pull the guts out.

Guts. The small spring can be discarded.

Now, to disassemble the plunger assembly, you must slightly compress the spring in a vise and remove the snap ring.

Here's the plunger assembly apart. You will need to cut the plunger (lower left) at the arrow. The sping and the plunger to the left of the arrow will be used, everything else can be discarded. Note that I purchased a weaker spring than stock; you must cut the OE spring to suit your liking if reusing.

Next, cut the housing flush. You will need to weld on a cap to the back side. I can't weld aluminum, so I made a steel piece to fit over as a temporary solution until I can have another one welded up.

To reassemble, simply slide the larger spring in the housing, followed by the modified plunger, compress and reinstall the snap ring.
Voila, installed. Note my steel backing plate, which uses the reverse lockout mount bolt as well as silicon to hold it in place. Sadly, I still had to cut back a part of my floor brace to fit. I doubt that would be necessary for most cars, since my trans was pushed back an additional 1/2" due to the early LQ4 crank.

And finally a video of the trans in action. She rows through the gears beautifully. And, uhh, this clutch is... uhh... stiff.

I just did a test drive in 5 o'clock traffic. Despite the ridiculously heavy/grabby clutch, damn if it wasn't the best thing I've ever done to the car. I don't like the way the Pro 5.0 shifter handle is canted toward the driver, so I ordered a Pro 5.0 Mustang handle and Cobra leather-wrapped **** to replace it. As I understand, the size/thread pitch differs between the Mustang and Camaro shifters. I actually like the Cobra **** much better than anything I found for GM products.

I also put the rear up on jack stands a few weeks ago, and ran her up to freeway speed. It started vibrating pretty bad no matter the axle location (full droop or weight-on). I still need to check driveline angles (since it's a giant PITA with a car this low), but I'm still fairly certain that I need to rebuild the axle, and see if I can check axle balance just in case I twisted one like I did my previous driveshaft. The plan is to do so in the coming months, once things settle down.
Finally, I took her out to the Good Guys event in November, and had a chance to autocross her a bit (sadly, no photos though). I'm hooked. Though it had the negative effect of resulting in a strong desire for a front brake upgrade; stay tuned for that.
