Thanks, Guys,

The SM420 mentioned is not really the one I am interested in.

However, the references that 3B gave were. Any publications or forum sites that you could recommend to pursue this a bit further?

What would be the chances of anyone having any of this NP435 stuff squirrelled away? Bloke tried to tell me on another forum that they (remote controls) are virtually impossible to source. Other than posting onto forums like this, any clues as to how I could either locate one, or at least a proper download of them? My parts book for the G.M. version is sketchy to say the least.

We have had them, the normal NP435 by the hundreds in both Australian built Dodge Ford and International, but to my limited knowledge, never had anything fitted with the remote mentioned.

Cheers, Dave 64
