I ordered the struts from AJUSA.. The Excel-G's were about $266 with free shipping from there. They were in stock too, unlike the vogtland springs. Very comparable in price to the GR-2's.
Just look them up for a 2004 Chevy Monte Carlo, and choose the "w/special handling package" and you'll find them.
I have the struts in hand, i'll take some pics tonight and post them. They look just like the silver GR-2's except they are black and say "Excel-G" on them.
