The '77 & '78 VB's had a very short rear guard. Last time I checked the DC Plastics seemed to have the VR/V75 rear guard and the VB rear guard mixed up on their WEB site. I have a DC plastic opaque guard on mine and it fits correctly. The VB guard is full length and goes almost to the swingarm and has an indent for the silencer outlet. Unfortunately even the original guards almost touches the silencer on the 360 (OK on 250) and discolours and if your not careful with exhaust mounting will melt. There is also a "Maier" brand (not sure of spelling) which are also good quality.
