I have looked at the existing threads pertaining to my situation but found no helpful or useful answers. So heres whats going on: I got modified synchro keys from Jacks Transmissions to stop my annoying synchro rattle. I was able to remove the OEM keys no problem, but I cannot install the modified keys without removing the 5th/Rev Synchro Assembly (Not 100% if this is the proper name for it but I have pics for additional clarification) I have tried everything I can think of and used all the tools I have to try and remove this thing but to no avail. Can someone please tell me how the heck I go about removing this thing and where, if possible, should I be prying at? (the arrows are labeled, just include which one would be the ideal spot that is best for damage avoidance) Also included are pictures of a fellow who found a puller that seemed to work for him, but I cannot figure out how he slipped the arms between the gear and the synchro without damaging it... Anyway, here are the links to the pictures (they are big), thanks for reading and I hope to hear back from some of you soon! P.S. Do I need to remove the nut for the middle gear as well as remove the middle gear itself in order to remove the 5th/Rev Assembly?
