going by the pics, the blue cap was a lucas/motorcraft dizzy.....
spooky enough, was looking at an old escort today with the same set up..the amp was on the dizzy.
he had not long replaced the whole dizzy, including amp, got it off ebay, a recon which cost him about £45
had a look for the carb, no joy mate im afraid....unless you want to change the engine to a sierra/transit 2.0 ohc
not had a chance to go through rest of the bits, but when i can will have a look for escort cvh bits and let you know
