If you search on posts by me (thread I started) you will see DIY notes for the radiator. Use golf tees to plug small oil lines. Spray siicone down the side rails to help get the radiator to slide out more easily. Push up on the radiator from beneath the car if it is stuck in there tightly. Often the original radiator aftermarket (in my case of a 380sl the radiator from radtech was identical to original, heavy metal etc) is almost the same cost of a recore, mine about $300.
