It shouldn't be too bad. I would plan on a new set of springs. If you have young, strong legs, manual brakes shouldn't be an issue. You will need to use the early style engine stands from a 68 -70 Nov or First Gen Camaro. This will require cutting off the extension tabs welded on your frame, but they will bolt right on.
You may also need to switch to a big block heater box if you want to run a heater.
