Those tracks are fantastic!!!!!! You've just discovered a way to spend even more money on your kit....first the tracks....second aluminum gun barrels....third photo etch and finally resin after market details. LOL
Bad news of course is that you can't ssssttttrrrreeeettttccchhhhh Fruil tracks....but it's ok cause you don't want to.
In all honesty....you'll love them.
