Whoops - I've been looking up the spec of a 1960 4/4.
Brakes - yes the 4/4 of this vintage was drums, only the +4 was discs.
I can see some logic now to the engine size as it's not much off what was fitted when new. Car probably is a Series 2 4/4, and the standard engine was both small and by today's standards feeble at 1172cc.
Could well be 16" wheels in which case, not easy to fit VW centres and make stronger ones. But the wheels you have could be the later 15" ones.
Needs careful examination
