I have the bonnet seal that came with my complete rubber set years ago from SNG.
Yes, I know this is too short. It’s the trimmings.
it is fairly stiff despite having it bake in the sun for 2 days and sit under the bonnet lip in very warm garage for 2 days.
I recall that the old seal I removed, can’t vouch for authenticity, was very foam like. Has anyone purchased a “foamy” one and from which vender?
