I have four large (275 amp average forward rectified current) stud diodes that I'm putting into a bridge configuration, and now I'm realizing why manufacturers make them in both normal and reverse polarities . . . It would greatly simplify my setup if I had two reverse polarity diodes and two normal polarity diodes because only two separate heat sinks would be needed and less wiring (mind you this is wiring for a 230 amp circuit we're discussing here . . .)

Mine are 1N3737R (reverse polarity - 275 amp, DO-9 case, 3/4" stud) - Does anyone have 2 stud diodes of similar ratings that they would be willing to trade for two of my diodes? They would need to be 275 or 250 amp, at least 200 Vrrm and most importantly normal polarity (threaded portion is the cathode).

I can provide datasheets if necessary and I can add something additional to sweeten the deal if necessary - let me know - I have extra stud diodes (both 150 amp and 275 amp models).

At 275 amps, unless it needs to be flexible, I suggest busbars.

The whole point of having two different polarities of stud diodes is that the heatsinks can also be the busbars. Please stay on topic: diode trading only folks!
