I am selling a set of brand new NOS Muncie 4 speed transmission synchronizer sleeves or sliders complete with heavy duty forged synchro rings.
These are Borg Warner Power Brute (made in USA) high performance parts from the 1970's : part number T85B-15
These fit GM car Muncie 4 speed trannies regardless of vehicle brand : Buick , Oldsmobile , Cutlass , Chevrolet , Pontiac , Firebird etc
Chipped or burred sleeves will cause missed shifts and problems going into gear.
Worn synchronizer sleeve splines will cause gear "hop out
Synchro sleeves can also have worn or enlarged shift fork grooves which will also bring on the above problems as the shift forks will not be able to move the sleeves far enough to engage the gear synchro teeth properly.
Worn synchro rings cause gear grinding when shifting.
All these occurences are damaging to those hard to find transmission gears
If you're rebuilding your Muncie - do it right !
I will sell the rings and sliders separately : sliders - $125 , synchro rings - $100 (prices are FIRM !)
Please do not ask me to call you or for my phone number I will respond to all email and answer any questions - thank you
