'40 Garnish screws

[V8 Bob]

I need a few #8 slotted oval head screws that are close to 1 1/4" long for the windshield garnish in my '40. The 1" screws I purchased from Roy Nacewicz years ago are marginal in a few locations. I found some 1 1/4" stainless oval heads from the hardware store that work fine, but the phillips heads are out of place. I sent an Email to Third Gen but so far no reply. No luck with McMaster-Carr. Would appreciate any leads. Thanks.
Merry Christmas.
