Durst M670 which lens for 6x7

Hi,

I am in the process of purchasing a Durst M670 Color. I plan to use it with 6x7 negs. The enlarger comes with the medium format light mix box and I ordered the SIXMA 67 from Durst in Italy. The only thing still open on my list is the question for a suitable lens. Anyone here who has used the M670 with 6x7 and can say something about it? I will mainly do 8x10 prints, maybe an eventual 16x20, but this would not happen often.
I am not really sure which lens I can fit on the M670. Does it hold a 105mm? Or do I need an adapter ring for it? Would a Rodagon 105mm do ?

Thank you in advance and sorry if ask an obvious question
Dennis

80 mm rodagon would be fine

Eller Schneider-Kreuznach Componan-S 80 mm..

Thank you everyone, I ordered a Rodagon 80mm .

Durst enlargers although very good use a proprietary type tub mounting device (at least mine does). I was fortunate and the unit I have was made out of that enlarger for Agfa Corporation and came complete with the both "tubs". As far as the masking units those I found on ebay.
