Anyway, here is the repair.
I forgot to take a pic of the piece broken in two. But you will get the idea from this fabulous paint pic....
So I used a glue gun to glue the two piece back together and then fibreglassed the underside.

Then trimmed and drilled holes. This is so that resin can fill these and give a stronger bond when I fibreglass the top. I also grinded away a lot of the old of piece that was glued in.

Top fibreglassed


Then trimmed up....


And fitted. It actually sits way better than it did before.

While I was fixing this I got bored and thought I would make some headlight covers.

Not far off finishing, I will paint these black and post some more pics.
