Adrian, sorry no pics of the assembly. But, I do use his CNC bent shift rods for my 18 splined 'Hemi' box. I love em, just got out of the R/T,,went to the local Dodge Dealership. Shifts great.
If I werer to replace anything I would check the plastic bushings and C-Clips, any missing parts will make it shift more difficult. I also use Jaimie Passon's semi-synthetic fluid in my gearbox, but others have used motor oil mixed with transmission fluid for the same effect but I was concerned about the soft bronze parts so I went with a proven fluid. No worries about some detergents/additives that are harmful to soft metals.
