Check the shape of the C-763 Slide Spacer against the full scale template on DWG 41. I decided to make a bending jig since there was about 1/4" difference between the C-763 and the template. Make the bend on the C-763 to match the template. Completed the rear slide track assembly by positioning, clamping, drilling and clecoing the C-762 and C-763 parts together as per DWG 43, Section H-H.
