Sorry dvldoc I must've misunderstood your post, I thought what you meant was that the LF3564 didn't had a by-pass valve. And it was a glitch that it was not-compatible with my 4m40.

here's a pic of it, covered in plastic top-to-bottom not just the bottom as compared VIC(used). no place of origin though (got it from WnL)
