Hot Rods Grease shields

i have reproduction lincoln style brakes at all four corners, the kit supplies everything new except for grease shields. should i clean up the old shields and install them or go with out?

Clean them up and use them. If they are not needed what have you got to loose?

 

I didn't use them on mine even though I had some. It won't hurt either way.

 

Henry Ford, being thrifty, wouldn't have used them if they were not needed.
