Funny thing is, the lower just slides in the arm and then bolts holds it in place. Never had tools around the boot. Its about a 1/2" rip in the boot. Up inside there. Figured out that I can also slide a regular moog dust boot over it. So I ordered one this morning. Goin to knockout out the carrier bearing and rear shocks here in just a bit. Gotta work tonight, so not gonna do too much.
