Looking to purchase some OEM rear shock assemblies, but I'm seeing 2 different part numbers for my 08 TL-S. One is 52610-SEP-A18, and the other is 52610-SEP-A19. It does not appear there is a left or right for the rear unit... but every site I check out shows these 2 part numbers.... same price, same looking part. I see that the "A18" supersedes the "A17", but I see no such labeling that the "A19" replaces the "A18". Anyone with some intel would be greatly appreciated!!!
