Pat...When we ordered the front clip it was the OEM we ordered. We found out the OEM was changed to the aero dynamic frontal area design.
They do make a Pro Mod version and it is even farther away from the original design than this one.
We did start out to making a look a like of the old car but things have been updated and some that were not expected.
The progress went something like a clone, to a look a like and now to a look something like the old car.
Still have your list, just haven't got to finish researching the numbers.
