M939 v.s. M813 Front Lift Shackle

[cobratodd]

Are the M939 front lift shackles a fit for an M813 front shackle mounts? The info I have on the M939 shackle is that the pin is 1" diameter and 1.55" between the holes. I don't know the dimensions of the bracket eye on the M813. Any help is appreciated.

They should be. I bought some of the front lifting shackles directly from the guy who bought out BMY Harsco (maker of the M939A2 series) and they fit deuces, M809 series, as well as the M939 series. I think the actual shackle is identical on those trucks...although there is an older and a newer style. The newer style has more squared off shoulders, for lack of a better description.
