This is inexpensive solution for those who like to replace their clock with boost gauge in 930 turbo’s. The 2” gauge is too small to be installed in to 3.146 inch opening. The solution is to install larger Autometer gauge which is .25 inches shy off 3 inch target. The difference is made up by the custom rubber adapter and black painted aluminum ring supplied by us with this kit. Nether the ring or aluminum adapter are sold separately.
You will receive Gauge, aluminum spacer (so your new gauge does not fall in to the dashboard), rubber adapter, bulb gels red and green, nylon hose, and several barb adapters to connect this gauge. Please remember, you need to reuse your original retainer rubber ring, currently install on the metal casing of the clock.
