I have an opportunity to buy a 4" trailmaster lift for an 86 pickup. I own an early 89 (still early style removeable top) 4runner. I have looked at a ton of websites and in all of the mags that I have kicking around, and they only mention pickups.
The ones that I can find have a different part number for the runner. Is this just the different ubolts for the rear?
I am pretty sure that the crappy IFS is the same in the pickup and runner, isn't it?

I thought about just tossing in the solid axle, but this truck won't be wheeled hard, just some light duty stuff. My other rig is my wheeler.
The SAS is just too much money to do it right.

So all ifs front end crap is the same from 86-95, right?

Yes.
