i am putting a split bellhousing 4l60e in my car...
i was told that some 98 and up camaro's had them... however, i have it in place and i am having a problem using the stock crossmember...

does anyone know if there is a different crossmember on the 98 and up camaro's?

 

I would say yes, according to the pics:

I couldnt' tell you how much of a difference there is, though.
