I'm looking for a Crossmember for an 87 Mustang that will work with a 4R70W transmission.

Unfortunately, we do not have a crossmember to fit your application. The crossmember we have for the Mustang, the RCMFB, will work with the AOD, T5 and C6 transmissions.

Do you carry Mustang parts?

Yes! We have a range of products including headers, mounts, adapters, vertical links, gas pedals, and more. You can find all of our Mustang parts here.
