Re: 86 C10 Trailing Arm Conversion

I was not inferring that they mounted a stock crossmember under the frame. They made a custom one, however it works the same way AS IF you were to mount a stock one below the frame. The driveshaft goes through the hoop and in both scenarios the mounting brackets for the trailing arms are at the same height in the same location. Their custom member works out the same as the way as the way I mocked it up.

The geometry of this move has been questioned in previous posts so I was just asking for more explanation as to why this is poor geometry. I am just trying to fully understand because if I move the crossmember up between the rails it is higher than the HRH truck and therefore there is more angle on the trailing arms. It seems like all HRH vehicles strive for a minimal angle in the arms.
