Whats the difference in these Throttle bodies

[dugs600LX]

I have an 87 lx 5 speed, i was thinking of putting a throttle body/upper intake fro m a 91 gt with an automatic. Are they the same? Will this work?

Get new gaskets. Save you getting a vacuum leak. I didnt replace mine when i installed a 65mm and the car ran like crap so i took it off thinking it was the TB. A few weeks later I bought some new gaskets and reinstalled it and holy ****. Big difference. Vacuum leaks can be pesky no matter how big they are. Save your self the headache and get the $5 gaskets. Alot of people over look them.
