Lol its no problem man :)
I am almost positive that almost everything on the truggy is bigger, but I cant say for certain until I get home in about 3.5 hours from now.
As far as I know there is the 5b 5r and 5t, tho right now Im not sure what a 5r is, after I post this its a quick trip to google for me heheh.
Yup, the alu is definately the same colour on both buggys and the truggy, at first I thought maybe I got a mbx6, but it doesnt look like a mbx6 to me
