You paid £50 for the pair?! You would have been better off getting some rigid plastic ones off a Marea that was being scrapped.
Anyhow, yes the handles are quite easy to replace (says he who's done 6). Very fiddly but possible to replace quite quickly. More time consuming part is taking the door cards off!
