Lengths of Ford wishbones

[banjorear]

Trying to figure out what wishbones I have in my stash. I know the '32 because of it's 2" perch spread. Anyone know the lenght of a '33-'34? How about a '37? Thanks.

it's `32 because of the 2" boss? ... `32-`36 are all 2"

`28-`31 are 2-1/4"......`37 and up 2-1/2" also

`32 and `33/34 bones look alike.....except there is !" difference in length...i'll tell you once you give us the secret password

Most of you will find that your eyes will glaze over before you finish reading this, but here is the full scoop regarding the differences between the FACTORY STOCK 35-36 axle and the FACTORY STOCK 37-41 axle.
First, it is important to note that the kingpin holes and the wishbone holes are both angled on both axles. As a result, you get a different measurement depending if you measure them at the top surface of the axle or at the bottom. Bottom measurements are significantly wider. In my description, I'll use the measurement at the top.
The 35-36 axle has kingpin centers of 50 3/8 inches. The 35-36 axle has wishbone pin centers of 36 3/4 inches. (Note: the kingpin measurement is at the top of the axle, NOT the top of the kingpin. Again, that would be different, narrower, due to the angle of the kingpin).
The 37-41 axle has kingpin centers of 48 1/2 inches. The 37-41 axle has wishbone pin centers of 38 1/2 inches.
Now remember, these are measured at the top of the axle.
This would lead you to believe that the 35-36 front track is wider than the 37-41 track. It is NOT WIDER. The reason is that the 35 and 36 brake drums have a smaller offset than the 37 thru 48 drums. This makes the track the same.
If you put 37 thru 48 drums on a car with a 35 or 36 axle, your front track will become almost 2 inches WIDER than stock.
The drop height of the two axles are also different, but this is also not the whole story here. You will find that the wishbones are also different, and that there is a vertical dimension difference between the spring shackle pin and the place where the wishbone rests atop the axle. This though, can be the subject of yet another post.
Have any of you made it through this without nodding off? oHIo Jim

That was a great piece of tech. I measured my uncut 34 WB today and it's 47" from the tip of the perch area to tip of the ball, 32 is about 2in longer and anything past 34 will have spring perches attached to the wishbone.

32 wishbone is 39 inches between the welds on the wishbone.34 is 37 inches.
