It was a while back, but I seem to remember the quote being in the couple- few hundred dollar range. I also remember talking with several speedo/ gauge restoration shops and this being the only one to almost instantly say "no problem!" .
Another, realativly inexpensive alternative may be to scan a speedometer face, prep it in photoshop, have it printed and cut on a decal sheet and apply that to a appropriately shaped piece of frosted plexi.
( or perhaps a frosted decal sheet and clear plexi )
This one fell into my lap, so I'll be using this one to take apart, clean, and scan. Once digitized I'll play with the numbers to make the zero's small like the '74's and go from there. I feel more comfortable taking apart this one instead of my NOS '74 cluster.
