Hi, I have a Fiat Punto '53' Reg. One side of the wiper has broke. Basically the link arm has worn and come loose. I can fit it back together but after a few goes, the joint comes apart again. I've heard that i can undue the bolt from the wiper to remove the wiper which i have done, but found there is a washer/clip under the thread. Is this easy to remove? Once I have done this I plan to hacksaw the joint from the washer arm and drill through to enable me to place a bolt from the link arm back to the washer arm. Can any help? many thanks. Glynn
