I should have a photo a bit later. I took mine out last night. It has from left to right, Tach, Speedo, Fuel, Temp. It's all one piece with no overlay or anything, but I took the liberty last night of creating an overlay for it. Doing iit in white with black cobwebs same as the surrounding bezel, and the grill. Problem is I don't have a working scanner, so it took alot of measuring, creating blocks of color specific sizes, etc, to get the cutouts in the computer, print them out, attach them to thick plastic sheet, cutting it out and using it as a stencil. WHEW took me hours on end. As soon as I get a working scanner I plan on scanning the stuff and posting it for other users, but that might be awhile.
I can also probably edit a pre-89 W/O Tach to include the tach, it shouldn't be too difficult, especially since I have the speedo/tach mask on here I drew up, I just lack proper alignment of the speedo, plus the other two guages would be there as well.
Tore my arm up removing the cluster too as my arm is about 2 inches to big to slip behind and remove the speedo cable. I'm going to need the help of a small boned but strong woman to get it back on. LOL.
