They are not the same as 87-93 ones. I think the fitting is the same, but they are held in/on differently. I would stay away from the aeromotive ones. I had the baffle fail in mine twice before i bought a kirbin. No problems since.
here i am again... i had/have a kirban, but i dont/didnt have it on my car cause i wasnt sure if kirbans were a 1:1 regulator.. meaning every 1 psi of boost increase the regulator increased the fuel pressure 1 psi... so i went with an aeromotive.
both worked really well, i never had a problem w the kirban i just wanted to make sure
