I just put on the SSBC kit on stock 89 4 lug axles with 15" 10 holes for now.This setup fits perfect stock, does not move the wheelbase and bolts in with only a rearrange (tweak) on the rear line leading to the caliper. (it can be bent or cut and flared and routed very clean. the kit with the new master cylinder was less than 600.00 to the front door and they substituted a master cylinder to match my 76MM front calipers at no extra cost.
