These are hard to find in usable condition even for the later cars. I was lucky to find one barely usable from Gerry at Packards Southwest for my 1951 in spite already having several for the era in my stock. I have prewar ones too but I doubt any are usable without considerable work. So many Packards parts are easy to find but these were never properly reproduced to my knowledge so they remain elusive. I did buy some NOS retainers a few years back but even those may be sold out by now through the dealers.
