I didn't think there was even enough room to mount them outside the frame on the rear. I've got the front mounts installed but I just never saw how the rear was mounted. I like the crossmember version Chev4t6, is your truck stock height or lowered? I plan to do an axle flip and c-notch so I'm thinking the crossmember setup would be the best choice for clearance reasons. Thanks for the help guys! Any more pics are great!
