Bar far easiest is replace w rack originally used. And theres not much room up there for those other rack and spreader bar I linked.
carl is right.......you should post some pics of the rack though.
I don't mean to sound rude but it seems you don't have a grasp of how technical front suspension/steering geometry is. Nothing wrong with that but you will get into serious issues if you start changing the rack without at least a good basic understanding of how changing just one thing with the rack positioning or the mount locations of the inner tie rod heims even a very small amount will make drastic changes ,usually to bump steer ,that can/will ruin everything. There is a lot of discussion on here that I would suggest you search and study. We are,of course , always willing to answer any questions you have at any time but if you are set on changing out the rack to something different it will be in your best interest to study up a bit also. It will make a sometimes technically difficult task a lot easier.

That's why im grateful to be here so I could try to learn from some good guys with professional experience. What I have put a lot of thought into is trying to find a heavy duty rack that will line up exactly where the one in there is connected to the tie rod. Also I been looking at space in reference to the pedals. The rack mount in there is pretty high maybe like 2 1/2 inches (not sure) giving it a lot of room for change. Im thinking if I used an 11 inch rack and spread bar, move the rack mount and build a new one to accommodate, keeping the tie rods in the same position. I don't know bro, how does that sound?

I don't know bro, how does that sound?That is correct, tierod heims must go back exactly where they are now, both horizontally and vertically.And don't forget front to rear placement as well. All 3 dimensions/placements will have to be identical. Rack I linked with spreader bar is about 4" from rack mount on frame to where tierods would mount. Didn't know if enough room to make that work? That one you have is prob 1-1/2" And pretty sure, Fastcorvaire's rack snuggy works on that. Not needed to start, but over time they all wear inside, his snuggy has adjustment for takeing up slack. Very slick piece.
fabr is absolutely correct! like i said earlier.....moving my tie rod up 1\8" at the steering arm creates a 3\8" toe change at the wheel, in other words, bump steer. everything is designed to move in a certain direction, on the same point, at the same time. that is over simplifying things but pretty close. i've seen that rail run in person and lance does very good work, if not dead on than very very close. this is why i said before, something must be bent, also why i suggested pics. from what you've said i still wonder if the rack bar/arm is bent. i say this because the racks (rack and pinnion) i use are much stouter than those . i have bent 2 now, although they took a pretty good shot. one in a small washout in the dirt sliding sideways that put me up on 2 wheels and the other when i tried to go under a dune rather than over it lol long story but hit so hard i blew the ball of the heim out of the heim (low carbon steel teflon lined) fyi that is why double shear is sooooo important lol kept me from losing my steering altogether and why i went to all chromolly heims on my front end including tie rods!
