Hi Russ,
The flow chart is the same as the old SVA chart and plenty of people have got pre'95 engines through without a cat. Just need to check that the manual hasn't been updated but I havn't heard about any updates.
Contact Ford HQ with the donor Vin number and engine number and they should be able to write back confirming age of the engine. That should be accepted as proof of age of engine by DVLA/VOSA.

HTH BV.
