Hey Guys, one thing to consider when going to a MII front end is the original AD frame design has no welds. They were all riveted together which is part of the AD design. Most of the MII front end "systems" are weld in and require the frame to be boxed in to maintain the original frame strength. To box in part of a frame is a tedious job to make look clean and neat. With this concept in mind, I used a MII system from Chassis Engineering that bolts in the cross member and spring hangers and necessary hard ware and no frame boxing is necessary.
just an fyi
