Difference between 90-91 and 92-93 rear bumper

Well, long story short, I bought my car with a body kit.
I am still searching for part to change it all back to stock.
The guy gave me the oem front bumper but he said the rear
are all cut up.

Anyway, I found a black 90 integra in the boneyard with the rear bumper.
My car is a 92, are there any difference in hardware, and fitting?

There is no difference for mounting the rear bumper. But there is a visual difference where the 92-93 rear bumper flares out on the bottom more then the 90-91.
