'67-'72 vs '73-'91 Rocker Panel Question

[GaBnn3]

I've been trying to keep my resto as original as possible. I need to replace the right rear outer rocker panel in my 1988 Chev Suburban. Before cutting one off at a salvage yard, I tried to find an unused original. I found a place that sells reproductions for '67-'72 models. Is this the same as those found on the '73-'91 models. Thanks.

The 67-72 stuff isn't even close to the same as the 73 up. LMC sells what you need for quite cheap, might want to check them out.
