You only need two major components with a donor logbook ,and new chassis ., to get an age related . Ie ABC 123C donor gets you *** ***C reg but still classed as 2010 ,or whatever car .
That means you could use front and rear axles from a different donor to the engine , supply that book and register on an age related.
The Goods SVA is a list of exemptions from SVA rather than a definite list on its own. CC ran a series of articles from about May /June issue last years showing what is required ,how to register etc.
External projections don't currently come into goods so no need to shave handles . Lights don't come into test either but must be there to be considered a complete vehicle. It doesn't have to be painted or trimmed but it's a wise move to register it as soon as it passes before stripping to trim or paint.
Photo history of build up plus minimum length of bed which should be same as distance from engine bulkhead to rear of seat to qualify for test.
For legal road use after test it needs fog light , side repeaters and seat belts though none of these form part of the test.
Trust me , it's nothing you are not fully capable of and without detracting from a hot rod appearance, even the side repeaters can be hidden in belt lines and painted body colour.
