20% discount from where?Universal NOB 6.5x14 spacing:
Tube lugs 3.5”
P35 1 13/16” (sourced on DFO)
Lugs are definitely heavy duty when compared to the Black Magic. Likely not a better deal out there on a NOB if buying a BM on discount right now. Yet, if triple flange is your thing the improved strainer, butt, lugs, common spacing on some hardware, and updated badge places the Universal as the best value on NOB with the Ludwig name (especially at a 20% discount).
Edit: Also the BM has rubber gaskets on the lugs where as the Universal does not.
