1990 Fleer baseball

I don't have much luck with Fleer 1990. In previous attempts to secure Red Sox I have drawn a blank. Yankees a plenty though. This pack was sent by Jonathan in Toronto, it may be from a vending machine but there is no verification of this.
I still need 8 Red Sox from this set:

#266 Marty Barrett

#267 Mike Boddicker

#270 Rick Cerone

#274 Dwight Evans

#278 Danny Heep

#281 Rob Murphy

#283 Carlos Quintana

#627 Roger Clemens '86

There are 10 cards and a sticker per pack. There is also a possibility of a Sammy Sosa Rookie and the lesser known Ripken (Ripkin) error card.

The pack:

#105 Luis de los Sanos Royals

#112 Charlie Leibrandt Royals

#372 Mike Dyer Twins

#387 Gary Wayne Twins

#428 Luis Quinones Reds

#434 Scott Scudder Reds

#437 Jesse Barfield Yankees

#440 Greg Cadaret Yankees

#442 Bob Green Yankees

#450 Dale Monorcic Yankees

Yankees sticker

The less said about this pack the better. I refuse to believe that this is an un-searched pack. Four Yankees and a Yankees sticker?
