aussie cars had
9 tooth and 10 tooth starters and there were 2 ten tooth starters
9 tooth with the starter drive shaft in the middle of the snout of the starter motor had a 25mm pinion at a distance of 24 mm to the ring gear with a 2 hole mounting 110 mm apart.
the pinion shaft in these starters passes directly through the middle of the circle that you could draw around the D shaped end of the starter snout
used on aussie hemi 6 some slant 6 and some direct-drive-starter-motor US street hemis (prestolite version I think) and some Aussie v8s
flywheel has 146 tooth I think.
10 tooth starter (no .1) was the same as the 9 tooth starter in all but teeth and pinion size, It had parts number Bosch 9-000-063-054.
The gear was bigger, 27mm, so they offset bored the starter snout and used a different gearing in the reduction housing to achieve a starter whose teeth aligned with the same flywheels. This one has a fatter pinion shaft and it does not pass through the centre of the end of the starter snout (the end is D shaped, if the D shaped end was scribed out as a full circle the starter pinion shaft would not be in the middle) it is offset away from the ring gear. which is ok cos the 10 tooth cog is bigger by 2mm.
this starter was made due to the previous 9 tooth starter having a reputation for snapping its pinion shaft and stripping the reduction gears
cars with this starter can use the 9 tooth starter or this starter and vice versa
10 tooth big pinion part number Bosch 9-000-063-021
same as US 318 360 383 440 most 426 hemi
used on some Aussie cars but not all, tended to be used on 727 and a few 904 cars.
this had a 32mm pinion at 24mm from the flywheel also had the usual chrylser 2 hole mount at 110 mm apart.
I think this is the one you need. to all intents and purposes its a bosch motor body bolted to the more or less universal Chrysler reduction gear
it will fit aussie and US cars but probably has the big power stud and 2 spade connectors instead of 1
some experimentation with the case earthed would be necessary to fit it to a US car
if you buy a dodge Dakota/denso mini starter for a dodge Dakota or similar dodge truck it will fit you bellhousing but you may need to swap to a different pinion cog on the starter.
pinions available from 8 tooth 22mm up to 15 tooth 36 mm for denso starters.
so based on the part numbers above what have you got?
and if its this last starter any US starter should work....and it probably has the 32 mm pinion
if you are happy to take the risk get any mopar application Denso starter and spend £40 on the correct pinion and a pair of snap ring pliers if you need to

for mopars they basically swap pinions onto Denso starters in the 1.9 hp and 2.5 hp range and polish them up a bit
