76BlueZ

Hello, I purchased a 76 280Z a couple months ago and it runs and drives great but I have a problem with the turn signals and high beam. When I move the signal stalk, I have left turn signal, but no right and when I pull back the high beams are inop. I bought a turn signal stalk/switch advertized as fitting a 76 but it was the wrong size. The month/year the car was built stamped on the door plate is 7/76. I want to buy another new switch, but don't want to end up with the wrong part again. I checked JC Whitney (carparts.com) and they have a part with stock # HLS1026 and they want $183 for it. I'm trying to make sure I find and buy the right part since I can't find it anywhere locally. I'd appreciate any help/advice on how to find this part or fix the problem. Thanks! Dan
