I would reach out to Coker by telephone, I purchased Firestone Wide 60 Ovals for one of my cars. The balance never seemed correct. After some time had passed, I took them to be rebalanced on a Hunter Road Force balancer. Shop said two would balance and two were not acceptable. I contacted Coker by phone, and they sent me two new tires freight free. Just my experience.

Thank You

Local dealer has this 67 convertible on his lot. I'm not too familiar with 67's. Looked at decode info on site and think I have it, but don't want to give him bad info. It' red, black top badged as SS, original motor gone. Insite? Thanks

Thanks for the info. That's a longtime for that casting to sit around before assembly. Nova rearend must be all the same dimensions as it bolted right in the 67 Camaro.

Casting # and larger stamping pics.

I'm a little confused by the coding on this rearend. Maybe I'm reading the charts wrong. The casting reads C289 (March 28 69). The housing stamp reads C  BL 0120G2 (3.07 open January 20 Detroit 2nd shift) right? And why the C in front?

I have a stock 69 Z-28 cooling system with all components as original with the exception of the removal of the smog pump, now using a shorter 7440 XL gates belt. Was having a heating problem at low speed and idling in hot weather conditions. The fan clutch was an Eaton unit purchased over the counter from GM in the 70's. Noted that the fan would free spin for many revolutions after engine shut down with a warm engine. Determined that the fan clutch was faulty and sent it to a respected restorer/rebuilder for overhaul. Received it back and overheating issue went away. Now I am noticing squealing which I believe is belt slippage above 4500 RPM. Belt has been replaced and is tensioned properly; all pulleys appear to be in good condition. I am suspecting that the fan clutch is not disengaging properly causing high belt loads at high RPM. In John Z's cooling article, referring to fan clutches he stated, "most of them essentially disengage over 3500 RPM" Sorry this is so long. Any thoughts?

There is an old thread on this subject that had some great illustrations attached. I saved the link, but I can't access the photo bucket images anymore. Does anyone have the info that can be reposted? Thanks

Thanks for the info. Can't remember any finish except rust on mine when acquired in mid 70's.

Were JL8 calipers originally painted, or were they natural iron?

Personal preference, but I have a GM over the counter chambered system, and I love the sound. Does not have a harsh deceleration rattle. I've had Z's with transverse and chambered and much prefer chambered. i have heard that the aftermarket chambered systems do not sound the same.

I was checking compression in my 69Z and was jumping the starter with an external switch. The service manual states in bold text to disconnect the distributer negative terminal and turn the ignition switch on to avoid damage to the ignition switch grounding circuit. Never had heard of this but did it to be safe.

Ran one under an OEM cowl hood for 40 years. GM small base short element filter, fit just fine.

Missed the stripe change in the E-Bay description. Thanks

My 69 z-28 is Garnet Red with white stripes and the paint code is - -. Was under the impression that white stripes as opposed the default black called for the special paint code. This car has a 52 52 paint code. My car was built in LA maybe different code? Just curious.
