OEM Front Swaybar End Link Size?

What length are the front swaybar end link(s) supposed to be for an otherwise OEM-spec 87 TC suspension?   The usual retailers all list a couple different fixed lengths for this application, about an inch different, and I'm not sure if what's on my car are the original or previous replacements (FWIW the rubber bushings are blue and the span between them is ~6", which is the longer of the two options).    

I've sensed a tickle of front-end play while making high-speed maneuvers and sure enough, the bushings are slightly worn... more alarmingly, one of the links was bent a few degrees.   I guess either link length might be better than that, but again I want to be sure I replace them with the proper baseline OEM length lest I introduce (or continue to chase) some other issue.

Any advice is appreciated!
