Yes their is a difference.
The early (67-70) has deep (1/2" nominal) locking strip. Looks like an "L" on the back side of the stainless.
The 71-72 have shallow locking strips. (3/8" nominal)
I would avoid the aftermarket stuff. It is difficult enough to install without the hassles of a poorly made part.
