1985 300TDT : Is the vacuum res. in the back (behind the fuel tank)( the big one with two rows of 8 bubbles) used for anything other than holding vacuum for the central locks and maybe the fuel door? I might make some art out of it if it is...The locks have a leak in them and I want to bypass them completely. Anyways...thanks for your input.
