Cortina Mk2 front brakes - disc only?

[foxtrot3]

Hi. The ford cortina owners club website ( http://www.fordcortinamk2oc.co.uk/home.htm ) has a link to a spare parts spreadsheet and it only lists disc brake parts for the front and drums for the rear. The mk3 Zephyr that came out a couple of years prior to the cortina only had discs on the front so maybe ENFO just did things a bit better than us or the yanks. Cheers MD
