After going thru the Junkion on the TFW2005 forums, i saw someone who had a G1 Modded Alt Silverstreak for sale. The difference between the G1 SS and the Alt is that there is that hood, roof and trunk are black on the G1, where-as the Alt one is all silver. I got an Alt Ricochet (who is black) in a trade and decided to do the same mod's to my Silverstreak. All in all, pretty easy with just some paint removal and some unscrewing. Check it out.
