240 2.8L air intake system

Just getting around to cleaning up all the little details on the Bertone restoration. The air intake system on the 2.8L V6 includes a heated air cold start system that picks up warm/hot air off the left side exhaust manifold. I think I have all the parts but cannot locate a picture of the system. Seen one before but can't find it at the moment.

Anyone got that that handy to share?

That's it.

Thanks!

OK, pulled it all out.

The bottom version, the most complex, is the '81 configuration. I have all the plastic pieces and the manifold heat tubing (#23). The larger, about 3" pieces, are not in good shape. The individual pieces seem to be the same tubing (#21 x2, and #18).

Anyone got any suggestions on sources or replacements?

#18 (948220) and #21 (1274131) are still available.

IPD sell a 240 pre heat hose, appears to be black, that I think should work.
