Ron, sorry for the delay... this one slipped past... yes the EXP500 is the Green Hornet.
This is my repli-bute to the car.
Lots of period correct parts, but no IRS as hand fabrication of one would have blown the already ree-diculous budget out even further... maybe some day down the track, but for now a standard 9" with 3.00 Tru-Trac (which was the original ratio in the car, or one of them as it morphed a bit as a experimental car!)
