info wanted about F15a frame

[Rob Baens]

hello i'm Rob and i live in the Netherlands.
I,m restoring a F15a 13 cab. I think it is a '45 model because the round roof hatch and bush guard mounted in front of the bumper. I didn't found any numbers yet.
Although the Ford was complete and in good shape it looks like the former owner has chopped the backend of the frame. So the bit is missing from the last cross member This is the part were the pintle and leave spring go.
My question is if somebody has got some info/measerements and pictures of this last section so i can reproduce this bit.

greetings Rob
