28 inch tires on 68 barracuda.

I have a friend who owns a machine shop and noticed my visits there he deals with aluminum a lot. I'm thinking that would be the place I will score the 1" thick aluminum. /QUOTE]

would you really need 1" plate? I mean, if 28 inch wheels fit fine (which they do on my car) and you went to 29 inch tall tires, you'd only need to move the spring hanger back by 1/2 inch to have the 29 inch tire clearing the front wheel housing the same as a 28 incher. 1 additional inch in tire height equals 1/2 inch on the overall diameter of the tire measured from the centre.
