Printing 6x7 on Durst M70

I'm currently assembling a darkroom for the photo club I'm a member of and we've managed to get hold of a pair of Durst M70 condenser enlargers for free. One is currently set up to print 35mm with a Siriocon 50 condenser and Componon-S 50mm lens, the other for 6x6 with a Siriocon 80 and Rodagon 80mm lens. However, several members also shoot 6x7 and have expressed interest in printing from that format so I'm trying to find out what it would take to set up an enlarger for 6x7 as well. I've heard that the Rodagon covers 6x7, but I haven't been able to find out what kind of condenser it would require. would the Siriocon 80 suffice or would I have to find another condenser?

condenser = VEGACON 100 for 6x7
lens = You need to use a 100/105mm lens.

Rodagon

Rodagon 80mm is actually specified for 6x7. Schneider80mm isn't, but will do as well. Schneider has the Apo HM 90mm for 6x7, which is very good.
You should use Sivogla AN (antinewtonglass) on top and the 6x7 frame on the bottom, they go into the Sinoneg holder.
Sorry if all of this is too late, hadn't noticed your post before.
