If you order a Strange Engineering rear end from us and choose the option to send in your stock brake backing plates for installation on the rear end we will contact you after processing the order to provide you with the RMA# and shipping address to send them in to.
Ship to:
Strange Engineering, Inc
8300 N Austin Ave
Morton Grove, IL 60053
Wait to here from us before sending them so we can provide you with the RMA# to mark on the box so when Strange receives them they know which order they are for.
