Components are largely interchangeable between 1G [1990-94] and 2G [1995-98] cars. However, it is best to check the aspects of a specific component, as detailed in 'Has anybody installed a [component] on a [DSM]?', above. There are a few gotchas between various model years that you have to be wary of. Component swaps between 1Gs and 2G, with few exceptions, should be researched carefully before the attempt is made.
