They are the same width. The IFS is identical between the two. Pretty much mechanically the same.
But its not a tacoma, its just a pickup. The Tacoma didnt come out till 95.5, and they are 60"
You could also try to find a fiberglass cap for that year pickup (or any mini truck really) and cut it to fit, maybe? I bobbed my cap when I first bobbed the bed, was pretty easy to do and they are usually pretty cheap..
