Had to replace my starter motor and thought I would share what I learnt.
Ford OEM $1300, Aftermarket $400 (no brainer)
Now there are two types listed for the 7.3 ltr and most probably will have to come from Melbourne so make sure you order the right one.
There is a long bodied - 3 hole mounted starter and a Short bodied 2 hole mounted. So take the old one with you when you order.
DAS Oceanic in Wetherill Park. Sydney. Ordered through my auto electrician. It shat itself on Wednesday, I was hooked up to my camoing trailer for a weekend away on Friday so I was in a panic to get it sorted. Turns out I should of stayed at home. Absolutely pissed down all weekend.
