BUILD-OFF CHALLENGE: Tygaboy's '75 LS3, It seemed a good idea at the time... Options

Hi World!
Let the games begin! (IMG:style_emoticons/default/piratenanner.gif)
As the title says, it's a '75 that's getting an LS3 (Cracker's "old" motor - thanks Tony!) and Boxster 6 speed.
Also planned is zippidy doo-dah 911 front suspension with Boxster calipers all around. The rear suspension is getting 911 ebrakes, Tangerine Racing raised pickups and shock towers.
I have plans to stiffen the chassis with a partial cage.

Doesn't that sound like a great plan? I think so, too!

BACKGROUND:
I got this as a roller that was purported to be "dry and accident free". And it was!
Except for all the rust and the place where it was hit. Yeah, yeah... But it's all good. The seller and I worked everything out. (IMG:style_emoticons/default/beerchug.gif)

But our little 914s are full of surprises and isn't that half the fun? So, first up is rust repair time! (IMG:style_emoticons/default/sawzall-smiley.gif) (IMG:style_emoticons/default/sawzall-smiley.gif) (IMG:style_emoticons/default/welder.gif) (IMG:style_emoticons/default/welder.gif)

Let's begin with some pics of what I started with. Wish me luck! Wait, forget the luck, wish me SKILL!!!

Chris - You don't need to have your bar that high - consider what I designed for you below (and if followed) - never look back.

The center support is important and I would not eliminate it from the design. The gussets at each end upright are absolutely necessary and should be implemented. Call me if you need to discuss.

I too will be re-configuring my cage in the next year or so - converting it to a more "hot rod" style like your car. I won't go any higher than the 4.5" (and probably even lower) from top of rocker to top of bar I've illustrated below when I do it (JMO).

Keep up the good work.

Curious what your thoughts are on simply running a tube from the rear shock tower straight to wherever is the best point in the front wheel well inside. One simple tube for maximum triangulation, no need for all the extra bits in the truss design.

I'm pretty sure that angle would make it tough to get in and out. If I remember, I'll mock that up and see how bad it might/might not be. Worth a look. Thanks for the idea!

Could be. But look at Sir Andy's car. His is easy to get in/out of. More swooped, but reality is, a bar like this doesn't interfere as much as you'd think. Sometimes it's actually easier to get in and out using the bar. And it triangulates the huge miss behind the firewall! That's an important part of this car, especially when you consider the worst rust weakening happens behind the firewall. Could also run an X tube to front suspension points.

Real cages and reinforcements have already been engineered. This is just brainstorming. But I figure this one red tube does more than all the black ones combined with less weight and effort?

Not trying to hijack your thread but Rand refers to Sir Andys roll bar setup. I haven't seen it and how it's done - any threads showing how he has it set up? Thanks, and now back to your regular program...
