what brnd oem type rad. to buy?

the 71 slant duster has sat for ?? many yrs before picked it up. got it running yesterday. orig, rad. has nice sized leak, it has been braized before, looking at the tubes f rom top, they look plenty clogged. I have had very little luck with cleaning and using these old rad., usually rotted. it had only a cup of antifreee in it due to leak at lower part of it. $ spent at rad. shop to have it boild ot and chcked general is waste of gas and $.
I can get oem style from o reilly which is Murray for $210, order from Rock auto spectra for 196 or a APDI/PRO for 219 shipped.
any experience with these brands anyone?????
NO I do not want an aluminum ra. on this slant. and NO pusher fans! thanks
I feel your pain. My old Jeep Cherokee radiator tank cracked. I bought a replacement rad from o'reilly. What a piece of crap! It was about 1/4 the weight of oem, because it was all aluminum and plastic, whereas oem was mostly brass and copper. The aftermarket rad would barely cool it on a warm day, forget about running A/C. It had a guarantee for 1 yr. It started leaking 1 month after warranty expired. Yeah, I would recommend against buying a rad from O'Reilly.
