Reproduction or NOS body mounts?

[vegaschevy]

I have a rolling chassis I purchased and it has a lot to be desired from where I thought it was described,

Some of the body mounts have cracks all the way through them where the bolt mounts, some are pitted VERY badly, and two were replaced and bolted to the frame and are PC black when all the rest are the silver powdercoat color of the frame and riveted.

The only way to salvage this and make it look good is to make all the body mounts black and bolt them all to the frame.

anyone make repop body mounts? I am not worried about riveting them ill bolt them to it I just did not know if I will need to purchase a frame to take them off of
