USCamera custom light seal kit fits the Leica R4, R4s, R5, and R7 cameras. This kit will not fit the R3 as that model uses a different body casting. This premium 11 piece kit includes 2 long channel seals on the body, 1 short channel seal on the body hinge end to counter lever, 2 channel seals on back cover (hinge end), 1 door hinge seal on back cover, short upper/lower back cover channel seals latch end, left/right mirror cushions and the film reminder window foam. Old foam removal and replacement information is always available online. Peeling the foam from the backing can be difficult for some. This video may help.
