Mendeola MD4S-2d Output Flanges for 930 cv.

I purchased a Mendeola MD4S-2D with the 934 Output flanges. I need to replace them with 930 cv flanges.
Weddle p/n is HV-5934L $371.20 and HV5934S $292.96 for the ones that I have, they are new, installed.
The parts that I need are as follows;
Weddle p/n is HV-5930L $282.01 and HV5930S $233.10
I will trade straight across for new parts, shipping on your dime, should save you $150
Or buy outright, let me know what you have. THx
