I bought a 69 version for my 68 (I liked the lower profile and black face) from the Parts Place a few years ago, but mine had 2 bulbs. I bought the "new technology" tach, not the direct reproduciton. I replaced the bulbs with LEDs and they are fairly bright. Now for the down side, I took mine apart so I could paint the housing. It has a gasket between the housing halves. Anytime it rains on the tach, it cuts out. Not sure if it is from me opening it up or not, but the next time I open it, it will most likely get 10 lbs of silicone. It was able to hook right to the MSD with no adapter which was a huge plus.
