Radiator Advice Needed

[rottenma@ei.dupont.com (Mike Rottenborn)]

Hello,

My New Year's holiday was marred by an unfortunate mishap.  While tightening
some hose clamps to fix minor coolant leakage, I broke off the fitting for
the overflow hose on the radiator of my '89 200T.  (I was even holding the
fitting tightly, to avoid just such an occurrence!)  The fitting was molded
into the plastic side tanks of the radiator and just broke right off.  I
bought a threaded brass fitting and a $16 packet of glue from the dealer,
and the car survived the 500 mile trip home with no problems.

My questions are as follows:

1.  Has anyone else used this repair?  Is it "permanent" or should I be
    shopping for a new radiator?

2.  Can a radiator shop replace just the plastic side tanks with metal ones,
    or does the radiator need to be replaced as a complete unit?

3.  Can anyone recommend a good source for a new metal radiator?

4.  How difficult is the removal/replacement of a radiator in this car?

Thanks for your help.  I appreciate any insights you can provide.
