[41woodie]

Blew a seal in my floor jack today which allowed the woodie to crash to earth and pretty much destroy the chin piece below the grill. I don't see any sign of a repro piece for a 41 but there are 40 repros available. Does anyone know how much of a difference there is between the 40 & 41 chin? If they are pretty similar I might be able to cobble one together that would work while I look for a real one. thanks
