I you’re building a VW long block from scratch, why not treat yourself to a brand new hardware set! This high quality set includes 8mm head nuts and washers, nylocks with washers for the perimeter of the case, the six big case half nuts with washers, 8mm through bolts, drain plate nuts, and copper exhaust nuts. Recommended for 85.5 or 87mm cylinders only! For 10mm head studs (most engines up to 71 and later.) New blocks supplied with 10mm case savers will also use this kit.
