  2. EEC Exhausts

    Has anyone tried the exhausts that are for sale on E-bay for about 120. They are advertised as being euro compliant and clearly have a cat as part of the assembly and a lambda sensor port. Given that the OEM decided to stop supporting this component many years ago, this seems to be an...

  6. Hood bar stuck in the open position

    I took the hood bars off yesterday. The passenger one went back on without a problem, but the latch on the driver's side is stuck in the open position, so I can't secure it to the windscreen. Any suggestions on how to unstick it?
