Ya all in here cracking me up.Yep rice in truth lol.Did some more investigation.Found the boot will fit back exact once the casing is removed.Only thing got to rig up sain now , cause it was done by someone and fitted back right without any problems , only thing he didnt have the knob.Another problem is the knob seems to be bracketed on to the underside of the casing

, so will try and find a fix around that lol.
