I had a CSF rad. put in my 96Q April 2007, works and fits perfectly so far. Not sure about the draincock,as I had it installed, and T3 did the only drain/fill as they replaced pump/thermo 11/07. Factory radiator cap fit mine fine, but I am pretty sure I got the aluminum/plastic end tank version,not the all metal one.
Go to
http://www.csfimports.com to search their catalog { 2 versions for the g50} and get their info on required coolant type,etc. I think I requested the model with the plastic tanks only because I felt more comfortable with the aluminum core as opposed to the all metal model with the brass/copper core{even though the all metal version is a thicker core and 2 row as compared to single row on the alum/plastic model}
