Value of a 72 3/4 Ton Disc Brake set up?

[67Mach1]

I found a guy selling a 72 3/4 ton rolling chassie and cab. It has BB motor mounts, heat shield and high hump center as well as auto column and shifter.

I pretty much know the value of all parts except for the 3/4 ton brake set up.

Is there any value in these parts outside of scrap? I dont see much request for parts lke these as folks seem to want to go to 1/2 ton components all the time.

Any information will help.

thanks,
Thomas
