Gotcha. Totally get it on the butt welds. Beautiful headers! Huge respect to the great welders.

The grinding comment just brought up the image of the "eagle crap" welds I've seen. (IMG:style_emoticons/default/biggrin.gif)

As usual, I'm all over the place. This evening, it was narrowing the flip rear trunk hinge. The Buick it came from is a bit wider than a 914...

I cut the cross bar in the middle then clamped each hinge half to the underside of the trunk seal channel, where that part will eventually be bolted. Then I tied the now overlapping crossbars to each other and determined center, then cut equal amounts off each side.

I then used the lathe to turn down a suitable bolt to make a slug that I plug welded into the cross bars. I'm determined to doing everything I can with TIG vs MIG and this was a good little project for that. So...A little TIG-ity, TIG and... one narrowed flip trunk hinge!

Finished installing the MadDog Motorsports front sway bar reinforcement plates.
I decided to to tidy up the rosette welds. Once it's back from blasting and epoxy prime, I'll seam seal around the perimeter. That'll all but disappear the wonky weld lines.

And the Elephant sway bar has their magical misalignment bushings. The bar literally swings, there's so little stiction. Really impressive.

Back to the flip trunk hinge.
I worked out the hinge attachment location. (Andy/Krieger was kind enough to let me measure and photograph his installation. Thanks Andy!)

I bolted the trunk lid to the stock hinges and adjusted the fit.
Then, with the flip hinge in place and the trunk shut, I can climb under and mark where to install the threaded bosses in the outer stiffener panel of the trunk lid.

I still have final trimming and finishing on that one part of the hinge so pardon the sharp edges!

That is going to be one impressive rear trunk lid. Cannot wait for videos of it in action.

Stephen -
Sure thing! In fact, I was thinking about you as I was doing this work, knowing you'd be doing the same install at some point. Once everything is in place and I know there's adequate adjustability and it all works as planned, I'll post some pics with measurements.
I can already tell you that to get things where I wanted them, the location of the hinge on my car is measuring out about 1/4" - 3/8" forward of where Andy has his.

The good news is that, near as I can tell so far, the specific location of the hinge (within maybe around 1" - 1 1/2"), isn't that critical. It'll be easier to document once I get it hooked up to the trunk lid and verify my assumptions about the geometry of this contraption!

This morning was fabrication of the flip trunk threaded bosses and reinforcement plates that I'll plug weld onto the underside of the trunk, along the outer stiffeners.
