lifts.. again
 

I'm restoring my 1972 GMC k25. It currently has 35s on it and only rubs when flexing a lot but the fenders are cut a little. It doesn't have any lift but it has HD springs so I'm thinking that's why its able to clear 35s. When I put new quarter panels on it will rub and I don't want to cut fenders. Im thinking of going with a 4 inch lift but I've read that it might rub some too. What brand would allow the most clearance? Would a 1-2 inch body lift require a bunch of other modifications? I would like to stay away from a 6 inch lift due to all of the extra mod$ required.
