Well worth the investment, but of course there hasn't been enough time for me to judge the long term reliability of the remanufactured actuator. I did end up having to pull off the front license plate frame and lower valance to get the old one out and new one in (not too difficult--only a few bolts to remove and put back), but now I'm completely free of vacuum leaks in the headlight door system. Works well and visually indistinguishable from the original. Easier in my opinion than an electric conversion and of course more authentic to preserve the vacuum system.

This item came to me in excellent condition. I sent in an excellent core from my 1969 Cougar convertible as well. Works fine and seems to have no leaks. Only time will tell if it lasts another 40 years but that is what I am planning on. Thank you Don for the hard work.
