Tom, I stumbled across some information about the Dukes of Hazzard cars while researching another topic. You may already be aware, but a race car chassis & fabrication outfit near Atlanta called Baird & Trivette used to do the Dukes builds, or at least they did according to this link;
Baird & Trivette Monza (scharch.org)
From the link:
"On another note, Baird & Trivette also built the General Lee cars for the TV series The Dukes of Hazzard. There were about a dozen General Lee's, all identically prepared by Baird & Trivette. It is said; the stunt drivers punished the TV cars more in one episode than a NASCAR team would in an entire season. The race shop had a surface plate (for squaring up chassis) reserved and set to General Lee specifications, for the 1968 and 1969 model-year Chargers that were sourced and converted. Three or four Chargers would arrive on a hauler. They would get stripped down, straighten, repainted and put back on the trailer, knowing full well the cars would soon return to repeat the process."
"Trivette now resides in the Ft. Myers, Florida area where his race car chassis manufacturing plant is located. The business produces mainly for Late Model drivers and for GT (grand touring) drivers."
I'm a big fan of local stock car racing as it used to exist in the South in the 60's, 70's, and 80's. I was aware of Baird & Trivette as regards their stock car chassis builds and crash repair, but never knew they built some of the Dukes cars until I saw this link last night. Apparently, as stock car racing started to fade in popularity, Baird & Trivette pivoted to building chassis for road racing.
Anyway, maybe you already knew about this, but I found it pretty interesting.
