Can someone with a 79-84 vintage cruiser confirm how the ebrake handle mounts to the transmission tunnel? Is it supported only by the sheet metal of the transmission tunnel, or is it reinforced somehow? If anyone retrofitted one into an earlier cruiser, how did you do it and how did it hold up? Is there any difference between 79-80 vs. 80-84 brake handles/levers? They look the same.... Thanks.
