Radiator frames, laser cut in mild steel, for DB4, DB5 & DB6. They locate the radiator cowl via 4 x 3/16" slots top & bottom.

Actually part of the radiator.

These are the 1st thing that you see on the top of the rad & the thing that rots out on the bottom of the rad, they also then stop locating the radiator fan cowl, to stop them rotting drill 2 x 5mm holes at each end of the frame - beware if you do this on a complete radiator as the rad will leak if you get it wrong !

When radiators are reconditioned these should be replaced if any corrosion is evident ensuring the radiator will last another 50 years.
