Tachometer Options 64' Chevelle

My Speedometer has a ticking noise coming from it and I don't have a tach. Is there any company that makes a period correct looking speedo/tach combo replacement? Would like to stay as close as stock/original as possible. If a combo doesn't exist, I would remove the center clock(still works) with a tach guage. Again, I would like the replacement speedo and tach to look factory if possible.
