Bowler Trans Tunnel

[AU Doc]

Does anyone know of a thread or install video for the Bowler transmission tunnel patch. I’m
getting close to pulling my old small block and I’ll be putting in an LS2 with a T56 Magnum. I’m expecting to have to do some tunnel surgery for the Magnum and I went ahead and bought the patch. Having never done this before, it would be helpful to get an idea of what is involved.

Thanks in advance.

I did find one thread with three pics, but it’s much help.

Alright, I'm getting closer and closer to putting my LS2 in the car for the first time (I'm working on the oil pan swap now). There's really not a lot of info on this on the web. I did email Craig at Bowler, and he sent me the DSE pics for reference.




For now, my plan is to lay the patch on top of my trans tunnel. Get it aligned like I want and roughly mark where it sits. I'll cut out the bulk of tunnel that needs to come out, leaving a couple inches extra above my mark. Put the patch back in and get it aligned again, then run some sheet metal screws into the lip I left to hold it in place. I hope I can cut along the edge of the patch about 6"-12" at a time. I'll try to make sure I either cut right at the edge, or cut through both the patch and the existing tunnel. I can peel back the lip from under the car, and put a couple tacks down to hold the tunnel where I've made my cut. When I'm done, everything should line up just right, and I can come back and finish welding and grinding.

Thoughts?

I have used the Alston chassisworks 1st gen tunnel cap. It fit nicely, has a stepped flange, and was fairly easy to install.

It looks like DSE did some massaging to the Bowler tunnel patch. These are the patches I got from Bowler. The short panel is not shaped the same as the the one shown in the DSE pictures and the longer panel looks like DSE put a bend in it.

I was hoping I would be able figure out where to put the panels without having to put the T56 in the car.
