Default Angle of dashboard?

Hi all,

What angle from the vertical should the dash panel (dropped-centre roadster dash) be?
There could be clearance 'challenges' for my speedo, so need to know how much I can angle-out the dash and still be correct.

Cheers,
Glen

On my 427SC, the dash panel is 17 degrees from vertical. This is not a drop center type, though.

Not sure about the dash but the firewall tilts forward, towards the engine. Makes for more room behind the dash.

Hi XB.
Cobra Restorers drawings place the 427 dash at 20*. One may assume they might be the same between models?

Dash at 20 degrees, so gauges at 20 degrees, where does the sun reflection end up when heading east in the afternoon?

Thanks.
If I'm working at somewhere between 17⁰ to 20⁰, that should give me enough room to accommodate the speedo and cable, and also the capilliary temp gauges.

Sun reflection? I'll look forward to it

Cheers,
Glen

I had not noticed it before, but this photo makes the firewall angle look substantial.


Also, regarding the dashboard, the top is attached, but what supports the bottom edge of the dash.

Let's tie it down to another reference point (because I do want it to look correct)....

Should the dash panel be approximately perpendicular to the axis of the steering wheel?

Here's a recent picture of CSX2075 (independent Dragonsnake, recently changed hands)




....and here's CSX2083 as well:




....and CSX2289, refurbished:




Perspective angles can be misleading, so comments from you guys more in the 'know' than I am?


Cheers,
Glen

On my ERA 427SC, the steering wheel angle from vertical is 15 degrees, while the dash panel angle from vertical is 17 degrees. So there is 2 degrees difference between the two.

Thanks Chris. That's the sort of information I need. It should look OK and I should have adequate gauge clearances.

Cheers,
Glen

Not sure about original cars but...
Superformance MkIIIs are about 8 degrees
Factory Five MkIVs are about 18 degrees
Even at 8 degrees off vertical the sun can reflect back when behind and low.
I like the IP closer to vertical.

Yes, fully agree.

I would rather a little bit of parallax error than a "whiteout" or blinded at the wrong time.

I'd rather have the dash angle correct to the originals and have adequate clearances for gauges.
If I end up having a reflection problem....easy, I'll just wait for sunset before heading home from the beach

Cheers,
Glen

Hi Glen,
The ends of the dash are curved inward and are mounted to the cowl/scuttle tube above the door hinge bracket. Also through the glovebox area if used. I would recommend additional bracing to the 3/4 tubes behind the middle as well. Check out 1985 CCX's scratch builds for detailed 289 build pics..

True replication at any cost! That's what I like to see!

Well Larry, there's so much under the skin on my car that's so far from the original CSX2xxx cars but I want everything that can be seen easily to be as close as I can make it to the originals.
OK, I'll be deviating in some areas, but it will all be period correct and in the spirit of each comp. and FIA car being set up for the individual driver.
That's my story anyway

Cheers!
Glen

Oh definitely! I want a five speed transmission, which of course deviates from original. Anyone who has driven an original on the freeway at speed would understand that too!
