These look and feel better than the originals. I'm confident they will help stabilize the rear end flex.

I haven't progressed on my project to test drive these mounts but I know from the high quality look and feel, these will be a definite improvement over the stock rubber mounts.

Brackets needed to be drilled out holes to small arrive on time and all parts there made a difference in driving but better when I took out the shims and put Caster in the right angle drives great

Jul 23, 2024 | Review shared from Total Bushing Kit with Transmission Mount; Black (63-82 Corvette C3)Mustang Rear Diff Bushing
This is a great product! It took me about 2 hours to change it out. I used an air chisel to get the inner sleeve and most of the old rubber out of the outer sleeve (you'll need to keep the factory outer sleeve to mount the new bushing). I had access to a lift, so that made it a ton easier! I then used a wire brush and an air rotory tool to vlean the rest of the existing rubber until it was bare metal. The rest was an easy install from there. It comes with grease packets in it. I used all of it!

If you absolutely need this for your Mustang; pack your patience. I elected not to install this kit. The instructions were adequate for properly installing this item and everything about the kit is top drawer. That said, to install this kit you have to remove the old bushings. Since I had a rear on the ground to practice on, I made several attempts to remove its bushing; it's glued into the cup. I hit upon buying 1 and 5/8 deep cut hole saw. Once the bushing is cut out you have to remove ALL the residue. Don't tear up your original until you fully understand what it is going take to install this item. Once you start there is no backing out.

Product fit perfect. Looks to be great quality. Very happy with purchase! Easy installation. I did drop my whole cradle though as I was also doing other stuff. Install took less than a half hour with the cradle dropped.

Old insulators would not work with new control arms. New ones were perfect
