Well, my original radiator gave me 125K of trouble free use, so if this one gives me the same amount of service, I highly doubt there will be any left by that time. I almost feel I should by one to keep as a spare, lol!
I was thinking the same thing. Actually, I've been thinking that about a lot of OE Mopar parts. Especially wear parts like cooling system components and sensors.
I know for a fact you'll be able to get u-joints and axle parts forever, since that stuff is used on a variety of vehicles other than just Jeeps. Once we're at the mercy of the Chinese though... Then I cringe.
