Ammeter to voltmeter conversion

How much was the Redline conversion, and how does the shipping work? I was trying to get away without spending the money for that but I may end up deciding to just do it.
Was $280 for the amp to volt conversion. Not inexpensive but they do high quality work and I've used them for all my instrument panels. I live in Ontario, Canada , so shipping is very $$$$. However, I live close to Port Huron MI and have parts shipped to a depot and I drive across to get them. Saves a lot of $$$ on shipping costs.
