87 to 89-92 tail lights
 

does the 89-92 taillights fit onto the 86.5-88 supras?

Not sure, because the first style has two independent lights, while the second style's brakelight extends across the back of the car to connect the two lights.

Yes it fits. Direct bolt on. I have an 87 with 89+ tail lights.

It will fit but their is 2 Tabs iirc on the middle section that dont bolt right up and you need to drill a hole to fit. That happed to me when I tried to put some 89 tails in my 87 but it did not look as good so I sold them.

Yep oldest mod in supra world
