Hello and Welcome,

That is an interesting story! 

Korves Oliver has reproduction parts, they should have the gauge and steering wheel. You need a better description of the air intake part you need.  Their website is <!-- w --><a class="postlink" href="http://www.korvesoliver.com">www.korvesoliver.com</a><!-- w --> , e-mail <!-- e --><a href="mailto:korves@htc.net">korves@htc.net</a><!-- e --> .

I hope this helps, John.
