Asslam-o-alaikum,
My cousin had a Toyota corona 1968 and he done some shocking features with the car as mentioned.
1. He made it 9 seater.
2. By removing back windshield and boot (diggi). 
3 By adding plane floor.
4. He also added 4 extra seats like Hilux Vigo:P.
Now the car completely looks like Toyota Hilux.
SADLY:( he sold it and I dont have pix. :'(:'(:'(:'(
But your suggestions about body and pix are most welcomed.
Any car should be discussed in this thread,
Regards,
ZEESHAN.
