Even so they are not that tough to get to. Either way it still takes time. As for the vented I have had 2 '95's and both went on me within months of getting them. 1st one had around 75k and I fought that thing the entire time I owned it until I removed the factory engine management and went with a Haltec E6X with a motronic wheel for the trigger. The opti worked fine to distribute the spark after that. 2nd one my current one has about 120k on it. I had to go into it within the first week of getting the car running clean it, sand down the contacts, etc.. I figured this would be a temp fix until I could afford to get the MSD. Well it ran for about 2 months, good enough for just cleanning it out and slapping it back together. But then again I might just have bad luck with the opti's!
