Are 75 wiper arms different than later Mk1's?

[mk1mark at gmail.com (Mark F.)]

Just wondering if I need the previous owner of my 75 to ship me the
wiper arms that he forgot to include.  It's been a few years, but he
contacted me recently when he found them.  Are the dual wiper 75 arms
any different than the singles?

 I've been chipping away at the restoration over the last couple
years, and it's almost ready for paint, so I want to start tying up
some loose ends...

Thanks,

Mark.
