IF you have a 79-98 Mustang buy the Granitelli Motorsport LCA's. They are 199.99. No need to spend 400+ on Steeda, or MM.
IF you have a 99-04 Mustang, DO NOT buy Granitelli Motorsport LCA's. Granitelli LCA's have 79-98 12mm holes in their bushings, so you cannot used your stock bolts and nuts. 99-04 Mustangs have 14mm hardware and are too big to be used in their LCA's.
NOW....Granitelli told me, "It's okay, you can use 12mm hardware, it's no big deal. Just go to any hardware store, and buy the nuts and bolts."
UMMM.....No dude.......It is not safe to put 12mm LCA's and 12mm bolts into 99-04's because it won't tighten up and it will eventually rip your torque boxes. It will also jump around and make noise on the axle mounting side. It's sad when the "tech guys" doesn't give a crap about you, and just pulls a marketing sales scheme out his ass to make more money!!!!
Anyways....79-98....go for it!!!!!!!!!!
