I need some help.

I have an oil leak coming from an oil line that is apparently between the turbos and the engine. I had planned on fixing it this weekend, however, finding the gaskets, as well as a repair manual, seems to be a bit of a problem. My downpipe is an aftermarket pipe, but I'm not sure who made it, will the stock gaskets fit?

Does anyone have any recommendations as to where I can buy these things?

Also, any other advice on removing the turbo assyembly would be greatly appreciated.
