Hillman Imp Saloon one piece rear body aperture seal

I am only maker of a bubble rear hatch body seal in one piece.
This seal is how later imps left the factory. Early mk1 imps had a flat rubber but it does not seal as well as the bubble seal.
Need to be mindful of the different length of locking latch there is 3 different versions so if the hatch closes hard look at a longer latch
