Meet Diane, my 1970 GS455 - A "Forever Birthday" gift from our youngest son several years back.

Thanks! Those are P235 70R15's.

Yes. I foresee the challenge... I need to verify the date codes and decide when I need to replace them as they are no less than 8 years old

Thanks! ...and yes, quite humbling. We must have done something right..

Indeed. Quite humbling. Apparently, when our son was 12 he used to watch me work on my '71 Skylark; seeing the satisfaction and listening to me talk about my dream car. He vowed one day he'd get me that dream car; and he did. I learned this when he surprised me 12 years later. My '71 is still in the family, as once I got Diane I gave her to my uncle for his final life project car (she needed a little TLC).

Indeed... Thanks!
