Clunking and Brake Light Question
Hi Guys I have a stock 67 that I'm wrapping up the restoration on. I have a couple of questions.
1. During take-off, my (completely stock) truck has a clunking sensation in 1st gear. As I release the clutch the truck violently rocks forwards. It feels like the driveshafts are struggling to transfer energy to the rear differential. Once in second the clunking starts to resolve itself and by third gear it's completely gone and the ride is smooth. At first I thought the clunking was normal but now it's a pain to deal with and starting to worry me. I have not replaced the ujoints and am wondering if that would help. Does anyone have any ideas on how to fix this?
2. I am trying to determine what activates the brake lights. Generally, there is a switch under the dash connected to the pedal. Mine does not have anything so it either did not have one or is activated differently. Can anyone advise me on what activates the brake lights? Also, is there any way to determine if your turn signal switch is bad?
