Channel to hold rear door seal on left C pillar
Seal channel to hold rear door seal. Attaches to left C post and runs from the sill up to the top of the C post. It is number 24 in the parts diagram.
These reproduction channels require some work to make them fit properly, but they are still the best we can find.
It is best to bond these in place with a suitable bonding sealer, rather than trying to weld them.
