on the front cvd's the pin can and has caused me problems. you can use #53 drill blank and make your own. drill blank stock is approx $3 ea or less and you can get several out of each piece. if you can not get drill blanks a #53 drill works by cut the pieces out of the solid portion
you only get two pieces per drill though.
also use a good high temp grease when assembling these - go to pepboy or a car parts shop to get a high temp wheel bearing grease.
put some of the grease in the spool and dogbone when installing in the car this will help eliminate some chatter and binding as well.
hope that helps you out
