As for the fork deal take a acytalyn torch (or if you cant afford that a propane torch might work might not be hot enough) and put a heating tip not cutting tip on it and heat the fork/bolting/mounting and heat it till its at least 500 degrees more like 1000 is better then take a bucket of ice water and splash it on there be careful though because it sometimes is under alot of stress and can pop off pritty quick.
