1. Yes, just a simple job. Need to reroute and resolder a few wires (to make a clean job). You will probably have excess wires if it was originally front wired, so you may need to cut the excess off and reconnect the battery connector.
2. No hands on experience, but I have heard less than stellar things. They are cheap, and it shows through. You're better off buying a pre-made gearbox from a reputable company. SystemA mechboxes are absolutely amazing. I've had two and they were both incredible, worth every penny.
I love freedom and consequently America
