Opinions on Transfer Case Shift Linkage Idea

Ok so I just swapped in a Gen I 350 SBc into my '88 YJ. I am running an SM465 tranny and np231 tcase with the advance adapter to mate the SM465 to the np231. I am toying around with the idea of a "solid" shifter/linkage. I would bolt a solid 3/16" piece of flat steel to the pivot arm on the t-case. The steel would be curved in order to allow for easier travel of the pivot arm and would have a t-handle at the top for me to grip on to. See very rough sketch below.

It's simple...it would work...but would probably have an incredibly long throw.

I figured it wouldnt hurt to try it since its just being bolted on. If it doesnt work I can always go with a novak shifter or fab my own linkage

Don't get me wrong, I'm not knocking it...I'm all for trying something different, especially if it's simple and it works. When you do it, show us how it turns out.

Will do. Not much use for it until i regear the front or swap in another axle with 4.10s. Plus i gotta find time at work to cut out the plate steel with the plasma cutter

Did you ever try this idea and, if so, how did you make out? I'm coming to the same point in my swap and have been kicking around similar ideas. I noticed there are a number of threaded holes on the passenger's side of the sm465 but it's too bad there are none on the driver's side. That would make things simple.

youngjeepr, did you have to modify the stock linkage? I would also like to keep the stock linkage but it's looking like I'm gonna have to fire up the torch and cut part of it away and do some welding. The SM465 is just so bulky it doesn't leave a lot of room and not much on that side to bolt to.

Yes I did. I mounted the shifter to the floor I'll try to get a picture of what I cut on the shifter. I also had to add about 2 inches to the rod.

Here is a rough sketch of what I did on my 5.3, th350, 241 combo in a zj. I used the shifters bucket where it mounts to the floor, then removed and bent the handle to use in reverse, simply to move it forward, then welded an arm on the pivot. Remember the longer the arm on the shifter the shorter the throw. Second photo is in 2wd, last is in 4lo.
