Picked up the engine, harness and adapter saturday from Sean at aftermarket 4x4. Ordered timing belt, water pump, thermostat, gaskets, rear main seals, crank seal and cam seal today.
The trail tough adapter kit comes with a spacer to reuse the samurai engine mount on the driver side. No need to buy new mounts.
Sean, reminded me that I can use the Toyota carb until I get the harness ready for the FI, so thats what I'll do.
