If it's still cooling the 351 adequately,and the only problem is a leak,just get it fixed.<br>I used to work at a radiator shop.Make sure the shop you choose pulls both tanks and rebrazes them.Get it hot tanked and rodded out while you're at it.If they offer to just fix your pinhole leak with a spot fix,walk away.Good shops will refuse to do that,and with good reason.If you spring another leak a month from now 3 inches from the hole you just had fixed,you're gonna be pissed,and rightfully so.<br>Lots of people have had good luck with Duff rads,they should last a lot longer than 3 years,and I think a pinhole leak is really no big deal,not worth buying a new rad over.<br>FWIW,I think Chuck's rad is the best available for EBs,but thats just my opinion.Dont have one yet,but when the time comes thats what Im going with.<br>Good luck,HTH,Rat
