Yet another car built in conjunction with the folks at Musclecar TV, our ’69 Trans Am convertible clone is really the alter-ego of the ’69 TA couple clone that started YearOne. The coupe is very important to us since the initial building of that car by Len Athanasiades resulted in the creation of YearOne some 30 years ago. As such, it will never stray too far from its current configuration.


But, we wanted an updated ’69 TA that featured many of the upgrades and improvements found in most of our other project cars. That meant there was only one thing to do – build another one. And of course the folks at RTM productions and Musclecar TV thought it was a great idea, and jumped on board for the build.


We acquired a good ’69 Firebird convertible body, and proceeded to replace the sheetmetal where necessary to provide a sound foundation for the project. The body was also mini-tubbed to clear bigger meats in the back, and the rear subframe was modified for the Detroit Speed rear Quadra-Link suspension setup. Up front, we used the Detroit Speed hydroformed front subframe, and beefy subframe connectors were fabricated to tie the front and rear together.


The drivetrain was based around a GM Performance Parts LS7 7.0 Liter engine. Rated at 505 horsepower, the Z06 engine retains the OEM titanium connecting rods and dry-sump oiling system. We used a custom serpentine accessory drive up front, and fabricated a stainless header and exhaust system using Magnaflow mufflers. Behind the LS7 is a beefed-up 4L60E automatic tranny, which sends the power to a Moser 9-inch rear. Monster Baer Racing 6-piston disc brakes all the way around throw out the anchor whenever necessary. Wheels are YearOne Billet Snowflakes wearing BF Goodrich rubber as always.


Inside the car we made our normal mods, including using late-model seats covered in original-type material. Classic Instruments gauges keep an eye on the vitals, while Vintage Air provides the heating and cooling of the cabin. The entertainment system includes an Alpine Nav head unit, with Boston Acoustics amps and speakers.


When it comes to ’69 TA clones, we now have the best of both worlds. The coupe remains faithful to the initial vision Len had for the car in 1979, while the new convertible makes use of the latest technology for better performance, comfort and style. What a great pair to have.
