First off welcome to the addiction
but beware, once you have one fiero in your driveway more have a tendency to show up.
If you are looking to replace you visors we put leather replacements in both of our cars.
Click Here "Mr Mikes" I can't seem to find the actual link on his site anymore for the visors, but just send him an email if you are interested. He's a great guy to deal with and the quality of work is top notch. If you come to one of the meetings you are welcome to have a look at the leather visors installed. I personally prefer the leather visors over the cloth ones, much easier to keep clean.
You should be able to get some stock gauges to replace the "custom one" in your car....
Mr Mikes again has leather seat covers, that's mostly what he's known for... however getting them across the border can be a tad expensive.... but if you are willing to pay the money they are an option, especially if you don't want to spend the time to create a pattern yourself.
I don't believe the car will pass a safety without a working e-brake.... I might be wrong, but I think an e-brake is a requirement.
