TF lower shocker mounts are the same both front and rear.
B&G list a repair kit using polybushes and a sleeve. Is this what you have found?

F shockers are different but maybe the same lower arrangement but TFs take more load.
New bolts are also worthwhile as they can fracture especially after removal and retightening.
