This shows both seals, however only one should be present. The foam seal BHH2270 was used on Mk1 cars i.e. up to Nov 67, the rubber seal BHH209 on Mk2 and later. I only discovered this after fitting the foam seal, of which I happened to have a length, thinking at the time it should have both.
And for completeness the buffers (one each side). Showing the general positioning relative to the front of the car (this is a V8 which has the same forward-mounted radiator as the 77 and later 4-cylinder models). Some say early cars had four buffers the additional two being near the rear of the side channels, possibly Mk1 cars with the foam seal. The Parts Catalogue only says 'as required' and although Clausager shows two cars with the foam seal it doesn't show enough of the side channels to see if they are present or not. One picture I have seen shows them situated mid-way between the two rear-most channel bolts.
Detail showing the right-angle bracket on the buffer being hard up against the inside of the channel.
