5x4" Hub Specs

If you do get your buddy to create some hubs, let us know.
I used an Allstar part number ALL48025 Proportioning valve for the rear drums. the funny thing is, when I was test driving to adjust the valve, I could not get the rears to lock up even before adjusting it. Not sure if it's doing anything, but since everything was working, I left it alone.
I got the Allstar on Amazon for 41 bucks. It came with the correct fittings; I did not have to re-engineer anything.
Good luck and keep us informed.
