Wow so much input, thanks everyone.
OK looks like the shocks are correct for the bike, now all I need to do is get them working better. I'll talk to RAD's next week.
Doc, I think the shocks with the internal dampening adjustment may be the 1978-C2 shocks, I've tried this on mine, pushed shafts all the way in without springs and there's no tell tale clicks. While they're at RAD's I'll get them to double check.
