I did manage to fit the shelf panel brackets, I fitted the rear shelf to the old brackets, the clecoed it to the braces and to the hinges, then removed the brackets and fitted the new ones, notching them to the mini tubs and clecoing them into position, before pulling everything apart ,again, and preparing everything for epoxy primer.
So with many hours in this weekend, you look in my garage and it looks like I did nothing..... But I should have all this Shot in primer and ready for final install this weekend, I hope Supposed to get to 100º this week, so not sure what I will get done after work.
