I just got off the phone with a local guy selling lonestar standard travel +2 a-arms, an elka rear shock, and a gforce axle. He said they're for a Honda but not sure what model. The elka is 14.5 eye to eye. Is this the same as my 400? Also what size a-arms will fit on the 400 frame? I believe he said the uppers were 6 3/4" inside to inside.
