Bosch door panel

I replaced the soap dispenser which I bought from Appliance Parts Pros, and for the life of me I cannot get the front panel back on. It has a row of metal tabs at the top that have to fit in a corresponding set of slots, and I can’t get them to seat. It was a tight fit when I removed the panel, but I think the main problem is that I can’t get them lined up with the slots and there is no way to see what I’m doing. Any suggestions or trick I can try? thanks
