The tunnel box is fine, but would use something different if your not running a console. Its not designed to be pretty. They make 2 different crossmember heights so they may have sent the wrong one.

From what i can tell, there are some differences in getting the right x member depending on the subframe your using?

thanks
Chassisworks was amazing. Very smooth fantastic piece. Every car in the shop getting a t56 will now use that tunnel. We have already used 2 of them. we will be doing another one soon and I'm sure plenty more. Use any crossmember and then shim the transmission crossmember up to get the correct angle.

Want to know something that everyone here forgot to tell you? No matter what you do 9 times out of 10 everything will have to be modified in some way or the other. There is no 100% this way or that way. Every car is different. STOP and I repeat STOP overthinking it.

Spend the $100, get the tunnel, install the tunnel.

Crossmember isn't isn't with angle. Thats easy to fix. The issue is where your exhaust will come in contact with the crossmember based on the headers you are using and how close you want the exhaust to the floor.

Notice the clearance.

I'll have a TMI console I'll be installing, but one thing I noticed is it's not as wide as my factory console. I was wondering if they had different heights, but couldn't find anything on their site. I'll have to see if I can get the measurements and make sure it will cover. thanks for the info!

I hear what your saying Randy, I know I'll have to mod the tunnel. I'm sure we will have to mod something else as well which is why I'm trying to get as much info as possible before i go out and buy parts that won't work or will take significant modification to work. Your point about where the headers/exhaust will come into contact with the crossmember is exactly why I'm trying to figure out the whole "swap" (engine mounts, crossmember, tunnel mod, headers, exhaust etc.) even though my post was specifically asking about the tunnel mod. I just recall reading peoples comments about "what worked best" and I can't find it so I started this thread. What crossmember is that? It looks like you've done a lot of modding to fit. I think I need to figure out what exhaust size I need soon as well. thanks for your help and I'm sure it will seem easier once I get at it!

I have a Magnum behind my Texas Speed LS3. I also used Hooker 1 7/8" headers. They don't have to be modified to clear my Lee 600 steering box, but the box has to be out to get the drivers header installed (at least I couldn't figure out how to wiggle it in there with the box on the sub). A header tube will have to be dimpled on each side to clear the Tru Turn tie rod ends if you go that route, nothing major though.
