I believe they are the same. It shouldn't be a problem.
The bushing style is different, but the mounting locations are the same, so you will be fine to use the newer style crossmember in an older car. Just make sure to match the bolts to the crossmember you are using, so if you used the newer style crossmember, be sure to use the newer bolts, and if using the older style crossmember, use the older bolts.
