So, in my search for a ZL1 I have come across a couple good deals on low mile 2017-2018 ZL1's... If I go with an early ZL1 I'd like to replace the OEM oil pump with a Katech pump. My question is, does anyone know of a reputable shop that they'd recommend in the Chicago area? Does anyone know if Katech might even do the installation? I don't think I'd trust any dealers to install an aftermarket pump, and don't want to go back to OEM if I'm going to go through all the trouble of replacement. Any help would be appreciated. Thanks!
