That speedo will be fine.

The drive shafts can either be 2 litre petrol/1.8 TDCi Focus items or MTX mondeo items, Gary has Mondeo on the fiesta, my S2 has the Focus setup. The centre shaft bolts the block, and they use a different bracket depending if it's Mondeo/Focus.

You will need 2 short (ie passenger side) Escort driveshafts as the long one is hollow and can't be used.
