Thanks for the info folks.
I had google mapped a route from St. Louis to Navarre Florida. It gave I64 to I57 to I24 to I65, a route i have been on. It also gave I55 to I22 to I65. Looks like they are ahead of themselves on the I22 part.
I think we have decided to take a 64 57 24 65 route. Been that route before to Athens Alabama.
I havent ever seen a bolt on spindle, like other poster said, the four bolts you see in the pic is for the brake backing plate.
If that spindle wont clean up, you can have a new spindle welded on. They can come to you and do it. But it might be cheaper to just buy a new axle.
To coat the wood, CPES, Clear penetrating epoxy sealer.
It is a two part epoxy that is super thin. Soaks down into the word.
We use this on floors and such in boats.
I get it from www.rotdoctor.com
Look into to see if it what you need.
