Finally getting a Triad exhaust for both 914's but want to get a new "shorter" rear valance for my '71. Need to replace my original "snow plow" valance which has seen better days after 45+ years... Just want to make sure the exhaust exit is in correct spot for the Triad. Going to make both cars have the same rear valance, and dimensions.
Would prefer metal, but is glass the only thing available?
