Eldo gas caps

[dxhall]

Anyone know of a source for early 70s Ambassador/Eldorado gas tank caps?  These are the ones with the locking lever.

Reproductions were available here, but seem to be sold out at present:

One word of caution with those though - the wide, flat piece on the underside that clamps the cap to the tank filler is a firm spring steel on the original. On the repros, it seems like plain mild steel - it bends easily and provides little to no clamping force and a leak is the result. Best to swap that piece from an old cap if possible.
