Looks like it came from the factory. Functionally superior to all others on the market!.
These factory fit kits feature a 270° sweep, 7000 rpm tach that installs in place of a factory clock or the blank space where a clock would have been. There are no dainty plastic faces or backings to deal with—this has a stamped steel face and backing with the correct factory face finish that will duplicate the other gauges in the dash exactly. This is a high-quality conversion with descriptive instructions and all the parts needed for installation.
Aftermarket product, usually an enhancement product.
