Might as well change all the tires out...And don't forget the fan belts they need it too...And I would'nt trust those radiator hoses either...Don't forget those rubber fuel lines they'll spring a leak and catch fire for sure...

You get the point...Draw the line where you need to... Funny thing about old cars...THEY'RE OLD !!! Did you expect everyone to NOT spend your money for you did you ???

You can do everything right and still have a blowout,fuel leak,rad hose burst etc...

I've seen guys do everything wrong and get away with it for 300,000 miles... That's life... Look at your car and change what does'nt make you happy...Or let me look at it from here and make the decision for you...

Ultimately common sense will tell you "it's shot" and time to change them..
