I mistakenly took my e-brake remnants to Cary's in OR, but he was kind enough to return them! So part of today was figuring where they'd go. The good news is that with a couple correctly angled holes in the lower cross brace, essentially straight below where they're sitting, these'll end up in the same locations as stock!
Love it...

Here's the planned location for the e-brake handle. Forward of stock and with no "cut out" but it'll do just fine. And yes, it's rotated forward so once it's welded in, the handle won't touch the floor.

I'll have to lengthen the connection to reach the e-brake cables but that shouldn't be too big a deal.

It did to occur to me until peering through the access panel but I have had issues with those plastic manifold connectors leaking. I'd suggest moving to proper braided lines...sorry for the late notice. Here is mine...its not pretty but its as tidy as I pull off. Come to think of it...the picture below IS your engine!

That is one plain looking water distribution block, it needs some 3D profiling or pockets or something to match the rest of the motor. (IMG:style_emoticons/default/smile.gif)

Will you be able to grab that with your back against the seat?

More progress on the "unauthorized" stock e-brake set up... (IMG:style_emoticons/default/shades.gif)

Next step is to braze them in, just like factory.

Then it was on to fab work related to the "inspection cover" area. The first step is to reinforce the area I removed.
So, out comes the roll bender and some 1/8 steel.

In place with some holes for rosette welding to the lip of the rear part of the fire wall.

Very cool!

Have you ever used the Blue Devil SILBRZ rod? It's a silicon bronze TIG brazing rod-not too expensive and works really well if you don't want to drag out the oxy torches and flux. (IMG:style_emoticons/default/smile.gif)

First reinforcement piece in place. Let's call this one the "inner" reinforcement...

...because here comes the "outer" reinforcement. I want this outer piece to be angled at a particular angle so I can use it as a take off for the removable inspection panel.

So, I started with a paper template. The fun part is to make a flat plate end up at angle but have straight edges, the paper pattern needed to be a curve.

Plus this needs to be roll bent... More fiddly, fiddly.
There was only a little cursing when I screwed up my first attempt. (IMG:style_emoticons/default/headbang.gif)

But with more, um "experience", Attempt #2 worked!

And the angle I was after?
The measuring/template making worked! (IMG:style_emoticons/default/aktion035.gif)

(the gap you see is because the vice grips pull it ever so slightly out of position...)

The angle matches the seat back. Silly, I know but there you go...

The real reason I need that angle, or something close to it, is to get the firewall forward enough to clear the fuel lines/fittings.

And once this is all welded in, I'll redo the cross bar.
I ended up not liking how much the initial design protruded into the interior space.
This is much cleaner.

And I forgot to mention, I'll plate between the inner and outer reinforcement pieces to tie the whole deal together. In all, it'll be plenty strong for the RaceRod.
