Hi Ismar
Thats is starting to take shape, the rails look similar to the ones McDonald Bros racing sell, I spent a couple of years working for them doing similar projects like yours, are you welding the x into the middle of the body or is that just bracing ?? Would love to have a closer look one day, if I can help answer any questions give me a ring 0412 81 1932, I live in Coburg . Peter
