My 110 is back on the road and it's awesome! I couldn't be happier so far. Tons of power, I can actually pull into traffic and drive on county roads without impeding traffic. Power steering is amazing and makes a huge difference. All that and it sounds cool!
All in, I've got about $6K into this swap, the biggest expense was the adapters and mounts. Not bad.
It's not as refined as my old 97 NAS 90. The NV4500 is a great standard transmission but it's a heavy duty truck tranny. It shifts like a truck and it takes some getting used to.
I haven't got any mileage numbers yet, still on the first tank.
This swap is totally doable. If you have any fabrication skills and can wrench (or have buddies who can like me) you'll be fine. The key to keeping it reasonable is when you reach a hurdle, slow down. I tended to just throw money at the problem and ended up buying a bunch of crap I didn't need instead of spending a bit more time on researching the answer.
