:)If you have the IFS year rear axle then I'd go with the 1.5 inch front spacers to get them even. I think the brakes are what make the difference in the early/late widths... If you go too wide, say 10 inches (haha), then your tires will rub on the fender under compression or limit compression. I have 1.5 inch spacers up front and an '87 rear axle and the widths are the same, using 10 inch rims/35 inch tires/generic backspacing. Hope my $0.02 helps.
