SU Carbs

[Mike <mikemurphy@iw1.net>]

I found two free SU carbs, linkages, inlet manifold, etc..  However I am unable 
to determine if I can use them on my '78 B.

The only markings I can find are as follows:
        AUC 8114 on the cap & damper
        AUC 871 on the carb body to the inlet manifold
        PDC 3 on the carb body inlet filter side
        AUD549R on a tag on the float chamber

Does anyone know what style these SU's are and can I use them on the B?

Thanks
