    I found a 1983 3/4 ton van with a 14B SF axle in it. The breaks are 13" The e-brake cables are both routed to the drivers' side. Are these the backing plates I need to make the 14B FF axle work in my 1990 rig? Do they just unbolt? Thanks.

    Measure the spring perches, I think you will find they are narrower on the van versions.

    There are two types of emergency brake cables. One type has the bolt on adapter, and the other has the press/snap in connector.

    Check out the type that is on your truck now (most likely the snap in) and then check the SF backing plates. If they are the same, it will work.

    When I did my 14B FF swap, I was lucky enough to get a 14B FF axle that had the snap in type of connector so I didn't have to change a thing.

    Thomas.
