Can someone please help me with SimEd?

[John Allen]

I've mutteled with this long enough... Can someone please give me a strp by step guide on how to convert a car from NFS HP to GTR2? I have the 3ds model,tryed to use parts from other gtr2 cars made the TEX,OBJ,CPIT and WHEEL files to no avail. I did get the car in to the showroom twice and on the track once but I have no clue of what the heck I did,LOL when the car was on the track it looked like a piece of cole with wheels,LOL.
Any help most welcomed... Thanks John.
