The idea of "restomodding" is enabling us to do things we've never dared do before with vintage Fords. Take the plexiglass R-Model back window for '65-'66 Mustang fastbacks for example. This plastic window was designed to save weight and operate as an air extractor in GT350 Shelby Mustang R-Model fastbacks when these cars were beating the pants off of Corvettes in SCCA competition. Did you know you can install one in your '65-'66 Mustang fastback today?

Tony D. Branda Mustang & Shelby has virtually anything and everything "Shelby" for classic Mustangs, including this groovy plexiglass rear window. To show you what you can do, we're installing it in a blown and injected 377ci stroker fastback at Duffee Motorsports in Phoenix.

Common sense must prevail, of course, when you're building a restomod. The Shelby R-Model rear window looks terrific, but it is impractical for the daily driver or even the weekend driver where rain often falls. The Shelby plexiglass window is more suitable for show cars and weekend play toys because, should it rain, your carpet and trunk area will likely get wet. Road noise is also a factor if you'd rather experience quiet behind the wheel.

Installing the Shelby window takes a lot of patience and an eye for detail. The rubber window grommet must be cut and trimmed to fit the plexiglass exactly. It's a good idea to lubricate the grommet and plexiglass for ease of installation. Otherwise, you install this window much like you would a windshield or backlight. We'll see how as Duffee Motorsports goes to work.
