open the skin.str file with your favorite notepad or word pad program
at the very top line it says: "car = G5 Rocket"
this is the chassis that is selected for this skin, you can change that to any other late model skin you want
for example
car = UMP Summer LM 1
*note* leave a space before and after the "=" equals sign
hope this helps if not just shoot more questions on this forums
