With the various components fitted and things tacked in place, the entire contraption gets pulled to weld on the bench.

Leaving the mounts attached helps ensure the hanger brackets stay in plane to each other during welding. Yes, the melty parts get removed before any significant welding begins.
The welds you see on the edges of the hanger brackets are to close up the scoring cuts I made to force the bend to occur RIGHT where I wanted it. This approach means that from the other side, the side you'll see, it looks like one piece!
Plus, this allows for a crisper bend which, to my eye, makes the part look a bit lighter.

Next was to CAD up a small gusset that ties one hanger bracket to the other.
If you look at the factory trans mount, you'll see a similar design - just nowhere near as stylish. (IMG:style_emoticons/default/laugh.gif)

I added these on the outside only. I'm leaving the inside open to allow for getting the nut and a wrench in there to install/remove the mount.

All welded and back in for a test fit.

It's always a bit nerve-wracking when you weld something out of the car then "see" if it still fits...
With things only set in place, not even bolted down, everything lined up perfectly. Man, I love it when a plan comes together! (IMG:style_emoticons/default/piratenanner.gif)

Last step is to bolt the mounts to the hanger brackets and weld the spreader plates to the chassis.

And no, that's not a missed weld at the gusset-to-cross bar joint.

@Krieger - Credit where credit is due, Andy. As I mentioned when this mod started, it was your eye for design and derogatory comments (IMG:style_emoticons/default/lol-2.gif) helpful suggestion that prompted the effort. If not for you, it likely never would have happened.

When you're next here, you need to sign the cross bar!

With all the dimensions verified, the transmission mount gets (mostly) welded in. I still have to get under the car and finish a could areas. But more than enough is done to allow me to remove the factory cross bar. And you know I've been chomping to get rid of it since @Krieger Andy first suggested I come up with a new mount.

I thought you might enjoy seeing it happen, so, here you go!

So here's the new look my engine compartment is sporting! I think it looks amazing.

So much tidier and a way better match to the vibe of the build.

"Mr. DeMille, I'm ready for my close up." (IMG:style_emoticons/default/laugh.gif)

I've been thinking about finishes so I figured it wouldn't hurt to give it a quick squirt of black, since that's part of a theme I'm considering: All the tubes in black, the body in non-black. Still not sure.

Something else that struck me was to have that big ol' main transmission mount cad plated, like the shifter bits you see there on the right side of the trans.
I think what's there now is too much black.

Here are the major parts that got removed. If anyone wants to move their Boxster trans and engine forward 1.5", let me know. I'll give you a good deal on some custom aluminum spacers... (IMG:style_emoticons/default/happy11.gif)

Saweeet! That looks so dang clean! Excellent work! (IMG:style_emoticons/default/smilie_pokal.gif) I would have suggested it sooner if I knew you were going to mention me by name in a video! (IMG:style_emoticons/default/lol-2.gif)
