Mine wasn't as bad.
This was over 10 years ago
I recently pulled it out again, since it was leaking, and had it re-cored with 4 rows of copper/brass. Decided to try to add some extra cooling capacity, since the car does get hot in traffic and on the track (even with no debris in the rad).
I also repaired the ABS plastic fan shroud with strips of ABS and ABS cement. Worked great.
Made a new bleed plug since the original one cracked. Made one in brass, and then figured that might get hot, so I made one in Nylon.
Had the AC condenser leak tested and put some new green o-rings in.
I had replaced the old top and bottom foam 10 years ago, but this time I decided to do something different. I didn't like how the foam could hold water against the radiator, causing rust, so I made my own rubber bulb seal and bumper. The purpose of the foam was to seal off the top and bottom of the radiator duct, so that all the airflow went through the radiator. I rolled some rubber matting and riveted it together with a flat piece on one side. Wedged into place above and below the rad, it'll provide a good seal, while allowing the moisture to dry out faster in my nice dry climate.
Lower seal firmly in place.
