These new 3 prong clips are worthless. I reused most of the old clips and used BW clips everywhere else. When I tried the new clips they were very loose and the expensive crimper is horrible
Spent a whole saturday to complete one seatback today. I got pretty efficient at bending up the springs at the end of the day.
This is my finished product. Added the tie wire for a little more lumbar support. The new springs a just a little thicker. I'm pretty happy with how it feels, but anything would have been better then what I had. The left side looks a little low but it measures out right on the dot.
Before/After comparison.
