We always convert our 240's and 740's to run the later style Volvo 940/960 e fan. They are cheap and easy to find. They come with a 2 speed relay. I always wire mine up to run any time the key is in position II. In summer, I run it on speed 2 and on speed 1 in winter.
I started an install on my '68 with the 960 radiator as well....
