I replaced mine this winter with a CSF brand, 4 core, radiator from MAF. It was around $300, and bolted right in. You will reuse the existing mounts from your old radiator, as well as reusing the two trans line adaptors.
Did not disconnect the AC system, just unbolted the AC condenser, and moved it enough to get at the mounting bolts. At the same time, I opted to replace all the hoses (22 in all – if I remember right
) including: rear heater, by-pass, EFI cooling hoses, oil cooler hoses, etc. Also replaced the water pump, thermostat and belts. Felt that it was time to start fresh.
Everything worked great, and I was done with it the same day.
