Since day one when my Grandpa bought the mustang (now mine) it had a rear chatter not sure why he never took it back for warranty, a buddy at ford thought it was a the rear clutch pack, it will chatter at a really low rpm and when im at about 30mph and then like 70ish mph, if i put it in 2nd when im doing like 20-40 i never get the chatter. When i was getting some work done at a shop they told me about an additive and while they were working on it i had them add some and it didn't fix anything they said it may need more but you cant add too much.. Anyone else ever have this problem?And what else should i replace while its all apart? And what are your guys takes on adding the <a href="http://www.latemodelrestoration.com/item/M4033G2/Ford-Mustang-FRPP-Rear-Differential-Girdle" target="_blank">Ford Racing aluminum rear differential cover</a> Will it fit mine without modding stuff or are there better ones?   What about these <a href="http://www.latemodelrestoration.com/item/LRS-4210A/Mustang-88-Rear-Gear-Super-Install-Kit" target="_blank">Ford Racing Rear Gear Super Install</a> and/or <a href="http://www.latemodelrestoration.com/item/AK-1563K/1979-04-Mustang-Rear-Axle-Bearing-And-Seal-Kit" target="_blank">Rear Axle Bearing & Seal Kit</a>? And im thinking about 4.10s, Wondering how bad it is on the freeway doing 80mph or more? (I don't drive a lot on the freeways to really care about saving gas but im curious about it) Car Info:97 GT AutoThanks!</blockquote>
