I've written a couple of places who pretty much just replied that their products wouldn't work to upgrade mine. It's been a while and I don't remember which companies I wrote to, but I gave up on using the FJ ends.

'89 3.0 4Rnr: Jacob's Electronics, K&N, CF Dual Frict, 4:56 w/ Truetracs, 33 BFG AT/KOs, Cascade Audio, Pro-Comp 4" susp & 2" body (previous owner)

I know, a lot of wasted time and money ... if I knew then what I know now....
