My 1971 RR heater core finally sprung a leak. All the replacements I find online are for cars WITH a/c.

My RR is a non-ac car.

Does my car have the same heater core with or without A/C?

For example I was looking at this: http://www.oreillyauto.com/site/c/detail...ord=heater+core

Also, I have never taken out a heater core. Does it really suck as bad as I have been told?
