I need to change my triple tree to a 5 degree rake to accomodate a Frankenstein Trike fear end. No one seems to know what tree to replace it with. Recently told the HD wide glide but not sure about mine being that wide. I did have a book with most of the parts used in Gilroy to put these together... but canĀ“t locate it. Any one know which tree to order??? Thanks Glynn
