New front clip rule

[JDracing57]

I have noticed that many of the new cars at my track have the right side frame rail cut off at the back of the block +/- but when I look at the IMCA/UMP rules it says it cant be cut any farther than 36 inches in front of the rear centerline. What am I missing?

Thanks

believe ump changed the rule.
IMCA is the same as it always has been and USMTS similar to IMCA here is USMTS
