This is bulk seal which you cut to fit your rear quarter light. Order one for each side of the car. It is the same as P55/15, but they have different numbers in the Jensen parts book, so I gave them different numbers here (the preformed seals P55/16 and 16/A are sided). You need either P55/15 and P55/15/A -or- P55/16 and P55/16/A - the 16s are the preformed to fit the window. By the way these fit MKI, MKII and MKIIIs, they need slight modification to fit the cars with non-opening 1/4 lights, instructons included.
Note - We are not currently offering the preformed seals due to fitment problems.
