What the Heck is this Transmission Part?

Ok so I don't know much about the various transmissions in our trucks.

- I have a 5 speed.

- It's supposed to be an LT77

- I have a wobbly stick that the inter webs says will be fixed with a new bias plate and or springs or herbal viagra.

- I googled images and then went out to the garage.

Here's what I have. Doesn't look like what I was looking at on the web. Here's are my concerns:

Notice under the end of the spring leg there is a hole for a bolt. There was a bolt (20mm? M6) with a jam nut making the spring leg sit very high and allowing a lot of side to side wobble.



I want to just leave the left and right bolts out entirely, bringing the spring legs as low as possible and putting constant tension on the shifter. Like this:



This looks like its contributing to the wobbliness.







I took it apart and cleaned all the gunk out of it. Ill grab some GAA tomorrow, grease it and throw it back in the truck.

So is this an early version of the LT77 or something else entirely?

Thanks

Oscar

Edit: I was wrong. John is right, it's an LT77 or R380 shift lever housing.

That is the Defender style shifter. Bias plates are on the Disco style.

It is missing the spring adjustment bolts. Look is the manual for instructions and pictures.

Disco V. Defender got me again.

I removed the bolts for cleaning and was considering leaving them out in hopes of snugging the left right action a bit. I think this is likely a bandaid for the nylon, or whatever, ball socket the lower shifter ball slides into. I haven't checked yet but I'm guessing it's gone and that's where I'm getting the slop from.

What issues would leaving those bolts out cause (easier to mistake reverse and first)? It might make the shifter center a bit better while I'm waiting for a new socket thing.

Shifter housing looks pretty worn out too. Has not seen a nice life.

I would grab a new one as well as the lever FRC7155 and FRC8724

Have a look under the housing and make sure the yoke for the selector is in good shape and it is tight to the selector shaft.

Thanks for the part numbers and the video John. The slick shift is going on my Xmas list.

I think I will order a new tower and gasket since I don't have one of those at all. The actual shift linkage was fine and so was the plastic socket piece.

I left the adjustment screws out entirely and it is much more... less sloppy.

Thanks again
