Windscreen Panel refit

I have just weldied up the bulkead and added some of the patch panels... not the best lined up ones ever but my first serious welding repair....

The pins at the base of the windscreen panels appear to be missing on the passenger side (there are 2 drivers side and 2 passengers), Is this something I really need to fabricate and weld on or should i just pop the panel back in with the top and bottom drivers side holding it in ?

Happy to hear your view...

I know this is an old thread, but my brother is having the same problems with his 110.

Have you got any pictures of the work you did please?
