I have both the Ejector Spring and Ejector Plate that I bought from Numrich Gun Parts. I ended up needing different parts and I waited over 30 days to return them.
Part numbers are 956130 and 956590.
The plate was $22.70 and the spring was 20.45 with $8.50 shipping.
I'll sell them both shipped for $40.
New SBE owner and new member here, so I can't post photos yet, but send me an PM and I'll send you the photos.
