(re # of teeth on input)
Vee_Que;115155 wroteIt was the same teeth with a different angle.
But re-reading the old posts, there was some confusion over the original shaft being 23 or 24 tooth.
Y'see, near as I can figure from going through various seller catalogs from US gear places, there are a number of different clusters which mate with a 23 tooth input shaft - some strong, some weak.
He started with a small bearing input shaft, changed it to the larger one which was the same and even still was the wrong angle with the same teeth. It just seems the Ef-au box was bespoke for the 6s. Plus the massive long main shaft to allow for the 24" shifter. Of course ba boxes are different again.
I doubt there is the data other than the Ford schematics given they are unique to Australia. The v6 mustang box of the same age is different too.
Which one? There are three different V6 Mustang boxes according to the book - Assemblies #220, #236, and #238. All had an identical ratio set (T5V), but had different overdrives, and only one had a 23 tooth input.
(speaking of overdrive ratios... 0.80 gears!

From looking through the US-centric parts catalogs put out by gearbox parts suppliers and doing a bit of cross-referencing, it would appear there's at least 2 different clusters that have the same input shaft tooth count, but are used with the weaker versions of the input shafts and gear sets. So, I wonder which version of US-based cluster is used in the Australian Ford 6 cylinder gearboxes, or if both the cluster and input shafts are unique Aussie things. Could be that the Ford L6 input shafts are all home grown - the only one I know for sure that is home grown is the one back on p.16 of this thread, for the BA Turbo box I have.
It appears the Commodore V6 ones are based on a US assembly. However, the V8 Commodore T5 uses the 1352-077-070 cluster, which is the same one used in the tough #251 assembly - which is often referred to wrongly as "the T5Z", but is actually a T5U.63 ratio set.
Is the mainshaft really any longer than most other T5s with an extension housing? Seems to me that the mainshaft visually appears to be the same length, and it's just the shifter that sits further back on the extension cover. Mind you, I haven't measured them and compared them.
Hopefully
@ratman will come back and answer questions before I have to pull my BA and ED gearboxes down for a discovery expedition. :)
