ok ive gota 95 gt with and aode trans and ive got a vibration when it shifts i replace the mount cause it had a broken bolt and that didnt fix it while under the car i noticed that my driveshaft it pretty loose in the tailshaft you can move it up and down about 2-3 mm is there a bushing or bearing in the tailshaft which i need to replace and if so how hard is it to replace. also when i replaced the u joints the guys at the parts store first gave me a set for an automatic which mine is they were to small so i took one back with me and the guy said the ones i had are for a 5sp could someone have installed the wrong driveshaft in my car?

 

you can't always trust a parts store so I'd research it on line a little and see if you come to the same conclusion as they did and or call ford and see if there are two diff part numbers..my auto equiped mustang did have a smaller u-joint than my 5 speed car and on the yoke of the auto car was like a balance ring..but all in all it shouldn't make a huge diff on the car cause I recently put a 5 speed driveshaft in a customers auto car with no problem as long as the driveshaft is properly balanced but a vibration during shifts may more so point to the tail shaft bushing...you have to remove the tailshaft= not to hard and then use a seal driver tool to tap out the brass bushing

 

ok thats what i thought well guess the bushing is the nest step in gettn rid of that F@#* vibration thanks for the info
