Hey Eddie, Give us a holler, it depends on where you are and what you need but right now most orders on line alone go out same or next day and to Texas is usually only 2 days shipping time. Finished suspensions are more like next day with the number of orders we have in line right now. But we always try to work with folks when they have a deadline for a trip.
Some lines are easier than others to splice, and even within the same family of lines the spicing can change a bit, green dynaglide currently has a heavier coating on it than the orange making it a bit tougher to work with. Fling it is a bit of a pain but it can be done, making the tapers a bit longer than normal will help to a degree.
