Regarding the aftermarket steering wheel horn: The truck came with a '76-'78 steering column, an aftermarket steering wheel, but the wrong adaptor kit so the horn didn't work. When I took it apart, I wired the horn to one contact (which I attached to the turn signal cam using Plastic Weld Putty). I also had to order the correct steering wheel adapter from Grant Steering wheels, as it came with a '66, not a '76. If you look in my other posts, you can see what I had to work with. I had to get other user's advice to determine the year of the steering column. Good luck.
Replied on the "for sale" thread. But I'll get it out when I get home, check the condition, how cheaply I might be able to ship it, etc. How does $30.00 plus shipping sound?

I do have a lot of parts left but, unfortunately, not the ones you list. I do have a rear chrome (Fey) step bumper with a very slight twist, but it is really heavy. If you're in the Central Cal area you can pick it up for free. I have a chrome front bumper too, but a little more work needed to straighten it.
