Ford Focus estate breaking help mechanic required to swap parts/break share in Hadleigh, Essex for sale

OK so I am hoping to do a deal with someone who is a mechanic by trade either now or retired/unemployed. I have a Ford Focus estate.1.8L and have now bought a 1.6L, same make and model. I would like to use the first to improve the second and have a tow bar to switch also. Frustratingly I have just had the front part of the exhaust replaced near to the cat and a new lamba sensor and crank shaft sensor in the last month. The Mot expires in a month or so and it has another fault which I think is fuel related and the garage have been unable to sort. The new car has an Mot till Dec, has full service history and is cheap so worth a punt! Anyone out there please who can help in exchange for spares they may need as cash is tight? I currently have access to a dry garage and a large driveway to work in/on. I will consider any offer of help, even paid so please contact me if you have anything to offer!!
