COPO 4.10 gears
 

I have a friend that would like to know the value of a matched
set of COPO 4.10 gears. They were pulled from his '69 Z/28 but
did not know exactly what he had. He gave me a call and after
referencing CRG's website I got back to him and told him what
he had. GM part #3916226 (ring) #3916228 (pinion) stamped
on them and dated April, 1969. Yes he is willing to sell them but
does not know the value. Also, being the purist at heart he would
like to see them go back on a real Supercar from that era. I have
tried to upload some photos but it's not allowing me to post them
because of an error. Need help posting these pics....Thanks in
advance.

First question; has he double checked the assy code on the rear axle to make certain it isn't a BE rear?

It is going to be tough to find a BE axle sans gears. Otherwise, they probably end up in a restamped BL axle.

I would guess he could get $2k to $3kfor them, but then I have not had anything like that in years. I believe the last set I sold was for $1,200, but that was many years ago.

Guys with COPO cars would know way better than I.

Guys with beautiful restored copo show cars are not redlining their motors and dropping the hammer so does it really matter if you have regular 4:10 gears or the hardened copo gears? Are the covers removed when the car is judged?

Agree with you in principle, but there are still guys out there that want the real thing.

Any purist guy wants the piece of mind that he has real parts. I have discussed this same idea at the Camaro Nationals. It is a way to set good cars apart from great cars. I am sure these are a matched set. But to help from people questioning them...pay the $50 and get them magged and give the buyer the receipt. $1,900 is your value. The reason they don’t bring more money is because your buyer pool is very small. So many guys don’t care.

$1,900 ? $2K? $3K? For a set of used dated 69 COPO gears?? -

IMHO - I don’t get it, you can’t see what’s in the diff housings unless the covers are off or you are Superman with X-ray vision. I understand the purists wanting to do Restorations correctly 100% like GM delivered but this stuff is getting pretty crazy. What’s next $1000 K for 69 dated GM gear oil? How about 69 dated engine bearings for $1500? I’m a purist too but somewhere you have to be realistic on restorations, or you will be buried financially into a Restoration. JMO.

Seriously it’s a good find and I applaud that the seller wants to reunite them with a COPO,
but ???

Any unique part for a rare car that has a date code and part # on it will bring a premium most people think is absurd. There's something about knowing you have the right parts for your car that makes it worth it IMO. Who would have dreamed people would be paying thousands of dollars for all the Ram Air Pontiac Quadrajets that got pitched back in the day and they can't be seen once their on car either. I completely agree with Doug though, things like this are what separates a good car from a great car.

You can’t discount that the hunt for dated coded, properly numbered unobtainium is very much part of the thrill for a lot of people restoring cars like these. It’s expensive, but is it’s own kind of fun. I enjoy finding correct stuff (especially wheels) but also question paying big $ for something unseen like a stock crankshaft and rods when good strokers are available to go bigger and lighter.

When you go to an auction ( not my way to buy a car) and 2 identical rare cars cross the block... 1 sells for $150k and the other sells for 300k. There’s your answer.

Update on gears/pics
 

Here's some pics of the gears...I managed to meet up with
him today and it seems that these gears are in pretty good
condition. Lynn, I did mention to him to double & triple check
the rear code on the housing--just to make sure he doesn't
have a BE rear as opposed to a BU rear under his Z/28.
