I know about the n1 truck carset on iwccars, but those seem to be repaints to resemble the trucks while still keeping the original model while the ones linked are modified 3do files.
EDIT: found out that the 1996 truck series mod for N1 is actually on the IWCCARS website, my bad! I just assumed that it would be the same like the 1995 supertrucks set
