These M8 bolts are used for only three purposes in all the Volkswagens in our range: for mounting the battery holder on the Karmann Ghia (1 piece), for mounting the cooling fan on the hub of the 1600cc CT/CZ and all Type 4 engines (3 pieces), and finally for mounting the rollers on the carrier seat of Volkswagen Bus ambulances (Bay Window Bus 4 pieces and VW Vanagon 3 pieces).
These bolts meet Volkswagen specifications in every respect. So please only use mounting parts that meet these specifications, and not something similar, as you may come to regret it later.
