Lighting question

[JoeKan]

Hello all,
My 61 back lights are not working and as bad as I hate to do it, I may have to take her into the mechinic to have him look at it. Before I do, I want to check in here. I'm not getting any power to the back sockets which I'm wondering if maybe my sockets are bad? I've tried tracing out the wiring, but it's a mess all the way up to the cab. It makes me want to yank it all out and start all over again. Any suggestions? The front turn signals are not working either (but the headlights are). I know for sure I'm getting power to the front signals and there is a faint glow from the bulbs. I'm not sure why though. I went to wal mart tonight to try and find the sockets and they didn't have any. I call an auto parts store and he said I'll have to call LMC. I called them and got there ordering service and she didn't really know much either.
While I'm on the subject, how hard would it be to change my tail lights to L.E.D. lighting? Would an auto store be able to provide or not?
I thought about calling them back but I'm afraid they know about as much as I do about it and that isn't much.
Thanks for the help if you can.
Have a good day,
Joe
