What do these clusters fit? Ford???

I've had these NOS clusters for a while (well, I picked the one on the right up on Thursday)........

i have edited the pic if you click on it...

what do they fit???

edit: forgot the pic.....and found a better close up too

 

Is there any numbers on the body of the gear?
Like WT-194-8 ?
The one on the right is earlier then the others.
How about teeth count,that always helps in ID'ing gears

 

the one on the left has 24 teeth on the 3rd set down....i counted them about 3 times praying for 25 or 26 teeth....

i'll look for some identification #'s........

there's a pc of tape on the one on the right and it's hard to make out but it looks like someone wrote on there 36-40? somone's handwriting usually doesn't mean a whole lot.....many people are wrong on stuff like this...i thought late 36 and up had the helical cut gears....

 

The straight cut one on the right is 32-35 style cluster, the two-***ter is probably around 39-47, the other one has the teeth cut the opposite way, I dunno if its Ford. Tooratly

 

The two ***ter is definately later style early ford.

 

Get 'em while they're young err.. early. lol

 

Lancaster, do you have 2 cents I could borrow?

 

Go to '28-48 book--detail pictures with tooth counts and dimensions of the various clusters. I think I've got an old Borg Warner catalog somewhere--no idea if it has enough detail to ID the non-Ford ones, but will look.

 

PS--All V8 Ford ones will be fairly close to same length, but there is maybe 1/4" variance even between types used interchangeably because they were made for a number of different thrust washer types, some quite thick.

 

Now that is funny

 

there's one in every crowd!!
