Welcome to the forum, MWDHAND. Hope you enjoy your stay.
My advice to ya is along guidry's line:
I'd do a lot of reading when you sign up. There are a ton of posts on a ton of subjects. More than you can probably think up. Use the Search box to get into the subject you are looking for. There are a lot of threads on shackles. Have a look as you can always ask questions right in the thread that is helping you the most.
Good luck with your truck!
