hi i have recently fitted a 2.0 zetec from a 97 mondeo into a fiesta mk3, i am in the proccess of fitting an oil pressure gauge to the engine but i need to order an adaptor that will thread into the existing whole where the oil pressure light sensor is but i do not know what the tread is that is in the block and im hopeing someone on here does,

p.s the car will be a lyden hill on the 3rd may if any fancys a look.
