Thanks for the replies.
I don't think welding is an option as the parts don't sit nicely together so there may of been some twisting before the break.
The second part number I don't think is the one I require as looking at this page,
Pelican parts
Part number 23 is the one on my car now and the one the breaker has sent me. The part I require is much smaller - about the size of the palm of my hand and woudl replace this part along with the other small piece.
That diagram is the same as the one I have. Does anyone know of an exploded diagram for the later roof please?
Thanks again.
