Ah memories. This is a bit off topic, but I used one of those hooks to make an adapter to mount a 61 VW bus transaxle, the type with the reductions gears mounted at the wheel end of the axle, to a 60 VW Beetle Baja. The hook came from my 69 Sportsroof with a 351W (4V, 4sp). We needed something quick and dirty and the hook was available. We needed to drill a couple of holes to get it to fit but it worked like a charm. I remember the date well, it was July 20, 1969. Our task was interuppted when my buddy's wife called us in to watch Neil Armstrong take "that step".
