GTU Optional Mark I Rear Fenders

Mark I rear fenders can be selected as an alternate on the GTU Body Package for customers who don’t want the complication of installing the door caps that come with the GTU package.
Mark I Rear Fenders are frequently selected as an alternative “extra wide” fender on the Mode One package for customers who need room for wide 10 or 11 inch tires on high powered cars. See the turbocharged 13B street racer below.
