Thank you Fellas for all the replies and useful information + recommendations.
Its been almost 2 months since I replaced the radiator for a Spectra Radiator I got on Amazon. I installed it and since the radiator crack I had was parallel to the metal frame I put some heat resistant foam on the edge of the frame (to prevent future cracks on same/similar spots). I decided to go for the spectra radiator since it came with transmition line conectors, lots of aluminum and it has a tougher material than the original one. Got it for about $85 with shipping.
