Well, I'm familiar with the picture posted above because it's part of a series that were posted for an Overdrive Transmission on an IL6 thread we just ran through.
To answer your question, the "U" shaped thing is attached to a "clutch release equalizer bracket" (7507 in the top picture in my next post) which is bolted to the side shifter plate on the transmission just above the shift levers. The "U" shaped thing is called the clutch release equalizer (or something close) (7572 in the second picture in my next post) Those two pieces bolt together with a sliding bolt so that 7572 can pivot when th eclutch pedal is pushed.
Funny thing about this picture is it's installed upside down if in fact that is a 3spd. They were installed that way on the 5 spds.
I have two exploded drawings I can post, but I have to scan them and put them in my gallery. I'll be back in a minute.
I'll be darned. Never noticed that. Guess I'll have to take care of that next time I'm out in the shed. Doesn't seem to affect its operation, though!
I wouldn't think that it would....basically you are just rotating around that hole that bolts up the "U" anyway, so that hole is in the same position.
The only reason I brought it up is I noticed in the picture you didn't have the shifters hooked up yet and I was thinking that perhaps it might have interfered with the back shifter later on and yo might have flipped it back at that point.
When I take pictures of things as I'm putting them back together, sometimes I will mis install a part, then have to correct it later on in the assembly...But I don't remember to mention it in the pictures.
If it works ok - go for it....I love these trucks, they are so forgiving!
Hopefully you won't mind if I ask a question while the discussion is on the brake/clutch assembly especially since there is a nice pic to reference. I'm trying to detach the entire assembly from the frame. I've got it loose but can't figure out what to take off so I can slide it through the frame rail. I'll try to take a pic and post. Thanks.
