Parts

[Numplumb]

Hi when the book came out it was based on ford escort, cortina etc they were cheap and plentiful, then they became rare and expensive.
Saturn made alterations to suit Mazda mx5 because they were cheap and plentiful, but now they are going the same way as the fords.

You can use just about anything if you can work out how to alter the chassis.
If you go down the parts route you can get all the parts you need for mx5 on EBay etc but you will have to settle for a Q plate.
Regards Mick.
