The bodywork is quite simple to fit and line up the worst bits are lining up the rear bumper holes and the fuel tank connection, the bonnet can be a bit tricky as its oversized and you have to bend and trim it to fit.
As for the brakes yes it fits in no problem but had issues with brake pedal travel see this thread

The seats are Marlin issue as per there pricelist a bit expensive and if I had the choice now i would go for Cobra Roadster seats.
