Chris:

Whomever you spoke to at Boca is not helping them, Boca DOES carry the bearings you need, they are the GRW D6900/603... they are just ridiculously expensive, they have 43 units on hand....see here:

Just so you know how this pricing act works out, here's GRW's germany pricing (select the 7th link from top to bottom on the left of the page for the D6900/603:

For whatever reason the only GRW bearings that Boca carries that are so ridiculously expensive are those for AMT turbines, the ones for the 280 are the same price...
