The W&P Sebring GT bonnet went on sale in 1967 and is a single piece fibreglass bonnet which replaces the front of the spridget. The front attaches at the front of the car by two front hinges to the front chassis legs and is clipped into place at the sides using bonnet clips of the same type used on the Triumph Herald and Spitfire. Externally it is characterised by the lengthy central "power bulge" modelled on the E-Type Jaguar, scooped headlights, and squared pouty air intake. Many have been fitted to racing spridgets over the years due to the design's combination of excellent engine cooling and good aerodynamics, and have had air scoops or vents added over the carbs or in the side panelling, but these may not be original. However W&P would modify to order, and if the modification has additional fibreglass which is coloured in a relevant 60's BMC/BL colour throughout (rather than over-painted), then it is an original factory modification, as W&P added the colour straight into the fibreglass. Some owners have also fitted their own grills to the air intake. Indicators and side lights were left to the discretion of the owner and the original early spridget ones are the most delicate. By 1968, Williams & Pritchard also sold headlight fairings and cosmetic half bumpers as options, in addition to supplying the front sprayed in primer if a BMC/BL factory colour was not chosen.
