Here we have the billet flush mounting plate. Specifically designed to slide right over the OEM 88-91 Civic/CRX (usdm) chassis, which should also fit many others as well. You will have to measure your opening to determine if it will fit your chassis as well. Inside dimensions are 53mm x 87mm, also included is a guide for you to use to drill out 4 small holes so that the plate can be mounted. The bolts will thread in through the back side, thus giving the floating appearance for a much cleaner finish.
They are available in Anodized hard black and Raw finish, pictured above. the universal grommet is included.
Plates are currently being made and expected to be ready to ship the first within the first 2 weeks of may 2021. Limied Qty will be available in both variations. Milspec connector not included.
Custom made locally, of 6061 billet aluminum.
