previous owner installed power steering but now it is very loose and i think the box is guilty. i would like to move it to use jt outfitters gear box bracket so it won't be in the way when i get bigger tires. can you help me identify my box, tell me whether to use the same kind of box or switch to a 79-85 toyota box as jt outfitters suggests on this page http://www.jtoutfitters.com/product/FJ4045GBI. the number on top of my box is 7812145 and on the round end is 5686815. thanks.
