what i have for sale is a vented msd opti with a low miles distributor cap. the opti needs to be rebuilt, however this is under 200 to have it fixed. it needs a new optical sensor. i will take 200 plus actual shipping. you should have under 400 in a brand new msd unit once you have it fixed or fix it your self. it is currently on the car. however, if interest is shown i will remove it tomorrow and it will be ready to ship on tues.
