Can't tell if it is a 420 or S type rear end but the panels and rear bumper on the trailer are better than those I have seen on a lot of cars.

 

Way better than mine. Which I'm very ok with. Better than new mechanically, so there's that.

Numbers stamped behind the rear bumper likely the only way to tell which rear clip it is maybe?

 

I was looking at this pic, hating the waste of another one to make a fairly attractive trailer when my enabling wife suggested that I have the raw materials to do it too. Now I am totally enthralled. Sometimes I just don't know what to think.

 

@jerry_hoback Haha you sound like a man with lots of inner conflicts. Just kidding.
Not a waste if the car's getting squashed anyway. I'm assuming he started with a rusty heap.....I hope.
The few nice parts on it could always be put on another car.
Looking forward to your trailer build!

 

That trailer is registered in New South Wales which is a state in Australia. Sydney is the state capital.
Twenty-five years ago, S types and 420s were as cheap as chips in Australia. Nobody really wanted them. The focus was on MK2s and E types.
The vast majority got snapped up by the hot rodders who wanted the rear differential cage, suspension, brakes and wheel track as an easy fit to their creations.
How this trailer came about I have no idea, but it was probably a "good idea" at the time
