I purchased a 1963 Ford 4000 and was surprised to find the tractor does not appear to have a parking brake. It looks like all that's left are a couple of teeth mounted on each side (near where the PTO dipstick is). I've looked around online and haven't found much on it for the 1963 Ford 4000. I'm hoping I can buy a kit. I have the 5 gear version and not the SOS so from what I've gathered online there is no Park like the SOS. Any guidance would be much appreciated.
