Shadow DN2 CanAm help please

I have been lucky enough to receive a DNQ one off of a shadow DN2 CanAm car for my James Hunt collection, but here's where I come unstuck having never built a CanAm car before I require a little help from those in the know, can anyone recommend a chassis for it Ive a couple of spare penelope pitlane chassis that don't quite fit, it's a fairly shallow car on height so the motor housing is pretty narrow I assume I need a rear mounted motor but am not sure which to go for any recommendations? Also could anyone recommend some tyres and rims to use that would look similar to the real ones. Many thanks in advance all suggestions welcome.
