Last post by MO - February 09, 2026, 01:39:27 AMTechnically, if they can't be validated, they should be removed. However, it's your car, and if you want to keep them on then do so. It really depends on what your goal is.

Decoding/Numbers / Re: Rare VIN Numbers
Last post by CNorton - February 08, 2026, 01:16:25 PMI've always been partial to VIN# with several consecutive zeros. Doesn't make them more valuable or option loaded but at least they're easy to remember. I previously had 8N300200, an O8C build and currently have 9N700017 built 10C.

Maintenance / Re: tire failure - check the a...
Last post by Mike S - February 08, 2026, 10:29:55 AMThe NTSB has posted on their site a few reports you may find of interest on tire age vs. auto accidents based on field investigations. Now, some car manufactures are recommending changing tires after 6 to 7 years regardless of tread wear. A lot has to do with the elasticity of rubber over time regardless of wear, and leading to sudden failures, with sidewall failures being the worst. One report shows the 8-year mark of when the incidence of the tire failure trend line rose sharply.
Here is a past thread for a tire sidewall failure that was spotted only after 2 days prior to looking at the tire before I took the car out: https://www.camaros.org/forum/index.php?topic=21292.msg193983#msg193983
Though I was fortunate it was easily spotted, it shows how quickly weak areas can develop.

Originality / Re: Big Block Timing Covers
Last post by boomer632 - February 08, 2026, 10:23:09 AMI picked this up at Carlisle pretty cheap last year on a hunch it was off of a hipo 69 motor. Note the 16- stamp and the corner of the timing indicator. No threaded holes for cover to attach to pan. For what I paid, I couldnt pass it up.

Last post by rich69rs - February 07, 2026, 10:07:30 PMJust had a new set of BFG Radial T/A's put on my '69 RS. The set of T/A's that were on the car were installed back in 2007 and had hardened to the point where there was a definite degradation / harshness in ride quality. The car rides much nicer now with the new rubber.
If you are not being attentive to it, tire age will definitely sneak up on you, it did on me,
No point taking any risks - and for cars that do not accumulate a lot of miles, tread wear is not what you need to monitor.
From what I've read, tires need to be changed at least every 10 years (if not sooner), regardless of mileage.
Although in the U.S., there are no specific laws prohibiting using or servicing tires older than 10 years, many (most?) tire shops these days simply will not service a tire 10 years or older due to the potential liability involved if it were to later fail in service.
I just ran into this when I asked the shop to put one of the old T/A's on my spare and they said no way.

Last post by KurtS - February 07, 2026, 09:24:10 PM9N711922 is the last VIN. 9N711910 is the last known car - probably are later cars.
