Did you know ford has a updated boot and pin kit?
kit #2c3z 2c150 aa
$30.00 one pack of two pins
This is suppose to keep em from locking up.
I bought em to see what the difference was . I like my mod,drill with a dremel a cut down the pin,fill with never seze.Its worked on the datsun for 25 yrs

cost a little time in the sun shine.
