G'day Norm, Tyler and all, Some of the PT starters are able to be rotated and others are not. The early type(pic1) with the removable "plastic ring" can be rotated in any of the 3 positions as long as you drill and tap the screw holes to match where you want to screw the ring back on. This allows for the piston to come right through it's stroke at bottom dead centre. The all alloy starters come in two types, the first(pic 2) being able to be rotated 120 degrees from the usual position again because it's got the cut away for clearance at bottom dead centre in 2 locations and the last pic which shows a starter that will only fit in the usual position. I hope this clarifies your starter woes a little.
