I measured, tapered and radius HS 710 & 714. I then bent the backwards sweep into each of them. The way I did it actually worked out really well. I used 2 scrap pieces of 2x4 in my vise, lined up the bend marks with the top of said 2x4, made sure it was level at 90 and used another scrap piece of 2x4 to apply pressure to the backside, which in turn bent it towards me. Slowly progressing the bend until it matched the bend in the already provide HS-00001 doublers. **See pictures**
