T's58 step side

[Bandit 13]

Hi everybody first time post. I have a mustang 2 ifs that was purschased off eBay for my 58 tf . The rubber boots are cracked or split. I try buying new boots from energy suspension, and the part stores. The ball joint at speedway are smaller in diameter, they fit like Chrysler 68 to 89. The ones I have are bigger but the dodge truck ones are to big. The only choice I see is to buy new arms at speedway. That will be pricey. Anybody have the same issue? Any help would be appreciated. Thank in advance Terry
