Early mk1 F had a different design hood and frame.
The early frame fits all models of F and TF but only the early hood fits the early frame.
Late frames fit all models too but only the late hood fits the late frame.
The early hood has seams that run front to back, later hoods have seams that run side to side.
The change over date from early to late hoods was mid 1997, half way through the run of the mk1 F.
