Windscreen wiper blade assembley for 1970 Morris

[TTO640H]

I have a 1970 Morris Minor sedan. I wish to identify the correct wiper blade wiper assembly for both the passenger and driver sides.
Are they identical in lengths or not. What are the correct lengths and how can I identify replacements by a manufacturers identification number etc for replacement.
Thanks

As you appear to be in Australia, these people may assist. I have used them even though I live in the UK, as amazingly they stock things that are not available through the usual channels here.

The link should take you straight to the wiper page.
