Unhappy Vintage Air and March Pulleys

I have a BBC with March Pulleys Performance set (Crank,wp,alt, and PS pullies) I ordered a vintage air kit and now think I am running into issues.

I originally thought I could use all my pulleys and just buy the additional a/c pulley. What the March Pulley guy is telling me is I will have to replace all my existing pulleys since I have the performance set which has a 5 3/4'' crank pulley and 6 1/4'' water pump pulley. The a/c set needs to have a 7'' crank pulley and 5 1/4 water pump pulley.

Is he for real, that would mean I have to buy basically an entire new kit . I really cant afford another $700!!

What are my options here guys?? ??? Does anyone run a vintage air kit with the pulleys I have??

Help before I get this AC

OH ya, The compressor I had coming also wont work it needs to be a Sanden 7 series?? Unless I mount it on the pass side
