Bell Tech MIGHT.
They do for the 80's trucks but here is some warning. It limits down travel and down trave is just as important as up travel on the ride. Good new is if you had to you could unbolt the sadle and all the suspension from a 87 and bolt it to your truck....yes I said bolt.

Mike has some good links on pre runner stuff. A lot of it will apply to your truck. He has sold that truck and not sure if he can be reached via e-mail off the site. Been a while since I have had contact with him.
