This is a package with 4 paintjobs created for the KART.
It's easy and fast to install, and don't need to replace nothing in GTA3.IMG...

You only need to edit the carmods.dat,
adding a new line that allows the kart can be modified in Transfender...

the line is:

kart, nto_b_l, nto_b_s, nto_b_tw

Now you just need to add the files

kart1.txd
kart2.txd
kart3.txd
kart4.txd

on your GTA3.IMG. No need to replace any files...

After this... HAVE FUN!

EDIT:
I up again the files, because i found a simple mistake in 2 of the 4 .txd's.
Sometimes, in 2 paintjobs, a little part of the color it's white.
Now the paintjobs don't have a white part...
