Will Ultegra brake hoods work on Dura Ace 7402 brake levers?

Here is a Dura Ace 7402 brake hood, that unfortunately was sold before I could buy the pair. I have identical brake hoods that are worn out and in need of replacement. While they do come up, usually in used condition, it is a matter of waiting a long time to find them, if /when they are offered for sale.

However here is a similar looking Shimano Ultegra brake hood which is readily available, has any one used this brake hood to replace the Dura Ace 7402 shown above? Will it work? Are their other brake hoods that work, such as the Shimano 600 brake hoods?



Thanks for your advice, also for any leads on where a set of Dura Ace 7402 brake hoods can be found.
