Thanks Duane. Might you have a picture of the QR bracket currently installed in the car?
And how did you fit the carpet over the transmission tunnel bracket?

Propeller Shaft Tunnel Bracket

I believe that reinforcement plate is designed to be installed from the backside. The instructions suggest cutting a 1.5" hole in the tunnel as the first step. It would probably be a little stronger that way.
Csarneson,
I installed it as the original diagram (Below) detailed, but installed the bolts in the opposite direction since it's much easier to get a small wrench to hold in the tight space than a Phillips. I'm guessing they opted for the front face installation so the reinforcing plate and the seat belt bolt would not be adjacent to the propeller shaft!! I agree it would be stronger the other way, but you would also have difficulty connecting the belt with the insulation and carpet. I'm hoping Olin will post pictures of his installation.
Thanks,
Duane

Here's an example of how I think they are supposed to be installed. It's not my photo. Just found it on the web. Looks like they plug welded it from the backside instead of using screws for a cleaner install. I don't think you have to worry about space for the driveshaft. You have lots of space side-to-side in there.

You (and Rick) are correct, the instructions very clearly state that the plate is installed this way.
Thanks Guys!

The only fly in the ointment is the installation requires the presence of, gulp, the dreaded "Assistant" to secure the phillips screws while you attach the nuts inside the driveshaft tunnel.

Even worse, the directions require installing the phillips screws from inside the tunnel with the nuts and washers on the inside of the interior!





Andy,Duane,
Great set of pics, especially the original mounting points in the tri-carb. If you have a photo of the inside of the tunnel mount, that would be helpful. The pictures in the thread above show the mounting of the "kit" with the six screws & nuts, where-as the original mount was welded from behind. In this set-up was the plate not extended to the chassis rail to give a bit more robustness in the design.

The inner nut is not welded to the reinforcement plate. That is unfortunate, because you will have to go underneath the car to remove the bolt anytime you want to remove the carpeting in that area.Duane - In picture a6 above, is the inner nut welded to the circular piece?
