Throttle/Kickdown Linkage....What Application?

I've got this throttle/kickdown linkage and I don't know what years or trans it fits. I know the throttle bracket is for a small block and I think the kickdown lever is for a 727. But I'm just guessing. Any help, maybe some pics would be appreciated. Thanks

Everything except the throttle bracket looks like 2 barrel Slant Six to me..
