Autometer 10K 5" tach with "recall" feature.... This is an "in dash" flush mount type monster tach. Dash hole size=3 3/8... The face says "Pro Comp/water resistant/memory" and the "Erase-tach-recall" feature is on a separate, remote (3' wire length), dial type switch, w/ 2 5/8ths round mounting plate.... It looks very similar to the #3990 shown on Autometer's web site.... The face plastic is perfect, no scratches or marks, crystal clear.....
(I will hook it up to my BBC and make sure everything works prior to sale.)...(3 wires, red, black, green).... It also has 4 and 6 cylinder options by clipping wire loops, but is currently set up for 8 cylinders.... Compatible with std and HEI type ignitions... NOT FOR USE WITH A MAG type....(Compare to #6801 memory tach @$249. Summit)
A good deal at $140. shipped anywhere in the lower 48.
