Charley -
If you are referring to a factory made motor bracket like one of the ones below - those ARE completely acceptable: :handgestures-thumbup:


If you are talking the factory drag chassis components / assemblies like below - then no - those are not allowed.
Hopefully that clarifies things.
If not - please let me know.
Thanks!
Todd
