FYI, the 50 resto cable is the made in israel piece that you find in the parts stores...
MFE is correct, although made in taiwan, it's the exact same construction as before, and is hands down the strongest cable made on the market, period.
Having said that, i've had experience with every cable on the market, and successful implementation involves several different things.
1. Although the adjustable cables are easily inferior in construction, their ultimate failure is not because of the way their made, rather it's the additional length. The adj cables are a couple of inches longer than the OEM non adjustable cable. It is this simple fact alone that caused me hell. This extra length still has to be routed the exact same way as stock. When routed this way, the cable is bent in a tighter arc, causing higher pedal pressure, binding, and wear, and eventual failure. Unfortunately there is no way to route the adj cable to provide a wider arc, it's just not long enough.
2.Routing is everything. I ran a cheap autozone made in israel cable forever without issues. The very first thing most people do is misroute the cable. There are only two different ways to route a stock cable The factory way is to the left of the motor mount, on top of the steering rack, and under the car to the bell. you can also route it under the motor mount and to the bell, but that's it. Most route it above the motor mount, inside the engine bay and to the bell. this is what is causing failure of the cables!!
3. There are different cables available. The 96+ cable is the "universal" cable that maximum motorsports sells. This cable is several inches longer than the fox cable, and allows a complete re-routing of the cable path. This is handy for those of you with long tubes. You can actually route it all the way forward of the oil filter, then down under the car, clearing the headers up top by a long margin.
4. I run an ADJUSTABLE 96+ cable on my 66 mustang/t5 setup and have absolutely no issues. I'm using a king cobra clutch, and pedal effort is so light, I can literally depress the clutch with my hand with little effort.
Anyhow, back to the point, the ford cable is still the best and strongest on the market...know your cable info, and you'll never have an issue with one breaking.
