They have smaller outer sheaths, they didnt stay in the brackets and kept sliding out. The connector that attaches to the throttle pin and the one that goes on the kickdown linkage, has a spring clip to snap onto the pin. It was not springy at all and stretched out and kept falling off the pins. I had to take a pair of pliers and pinch it shut over the pin. Which did not last long at all. The set screws stripped out upon final tightening. Just overall cheap. You get what you pay for.
Im sure some have had good luck with them, but I will never buy them again.
