How do I identify a straight axle?

How do I identify a straight axle? - 09/19/12 01:14 PM

A few years back I bought an old 65 Barracuda that someone had installed a straight axle in. The lug pattern was 4 1/2" dodge or ford bolt pattern with drum brakes. I got this to use on an altered wheelbase project but I would like to know what it is to research disc brake options. No pics as of now. Is there an easy way to tell if it was from an A-100 van? Thx...

I believe a pickup axle would be too wide, should be A-van or econoline.

Just read a similar thread on the HAMB.

They mentioned the bolts holding the wheel cylinder went in at a different angle on the Econolines.
The A-100s have 2 different sizes from the axle out. Gotta measure the drum size or failing that measure the bolt widths of the backing plates.
Look at this

If it was a Ford wouldn't it be a 5 on 5.5 inch bolt pattern?

Here is an A100 axle:

IIRC the Econoline with the straight axle was 5 on 4.5 same as the cars. There were a ton of them used under "gassers" and their replicas. Pickups would be 5 on 5.5, and I think they would be wider to boot.

Thx for the info and the parts schematic. I'm going to look at it tomorrow and see if it looks the same as the rendering. I noticed it has been cut in the center and shortened up. With my luck if it was in a 65 Barracuda it will be too narrow for a 65 b body.
