15 inch rims will fit on a 14 ff with either 11 inch brakes or a disc conversion, but not 13 inch brakes. Is this right? What about an 8 lug dana 44 or a dana 60. The reason i am asking is i thought that tires are more expensive for 16 inch rims and there is not as much selection. Is this true? Also on another subject, does anybody know what kind of tranny and transfercase is in a 96 z71 1/2 ton chevy pickup. (I know this is not about a k5,sorry) Thanks for the help.
