When you buy a factory in-dash tach, can you tell wich one is for a 6 cylinder and wich one is for a 4 cylinder?

Check this out. A 4 cylinder begins to redline at 5600 RPM's. The V-6 begins to redline at 5800 RPM's.

I have both but I'm keeping the 4 cylinder. I'm selling the V-6 cluster on eBay. It has about 5 days left.

I have two clusters sitting here in front of me. I dismanteled both for cleaning. The 5800 RPM distictly says "6-5800" in two places on the tach head. The front side top, in small numbers. And on the back side in large numbers. And my 5600 RPM says nothing. Maybe someone took yours from a V-6 and retuned it for your truck. There is a pot on the back of these.
