3.08 in a twelve bolt? Better check that information. Never had a Twelve bolt with a 3.08. 3.07 yes. If a car was special ordered with a 3.08 it got a ten bolt because that gearing was only available in a 10 bolt. Open or posi. My rearend on my 67 is a ten bolt. But the trim tag has a 4p which could be an SS350 or the 275 horse 327. It is a 4 spd sag. Build date for the car is Oct 66 I think the last week, from LA. The rear end code is also Oct 66 too but from the first week maybe. Maybe someone changed it out, but maybe not. I know that when I took the diff cover off it looked brand new with what I think are GM gears, it had what appeared to be GM part numbers. I bought the car in January 92 with a 6 cyl that had the frame mounts welded to the frame. The guy I bought it from said it was his wifes and she blew the 350 (racing) so her father put in the 6. The trans is something newer, from 69. When I bought it, it did have all the SS emblems and the 350 on the fenders. Even the early style SS350 gas cap. All the chassis numbers match the vin, and the vin and the trim tag look to be date correct. 21213 are the last 6 of my vin. It also had a RS front end with the back up lights stored in the trunk. The rear lower valance looked to be a replacement and there is an extra hole in the trunk for the wires of the back up lights. Front end did have the most of the wiring harness for the hideaways, and all four of the limit switches, but the car does not have the coding for the RS package. Missed on some of the earlier Camaros? Possible.
I personally would not alter a numbers matching car, from the original owner too. The car does have value being a L30/M20. Richs article is right on the money as far as I am concerned. I rember when it came out I was looking at my camaro with a fine tooth comb looking for anything that would deem it as such. Mostly just looking for a true Identity.
Because my car is altered from its original state the value is not that of an original. Point being that if its original, the value should be as such. Lets face it, in the past year or so the prices of these cars has risen dramatically. Ebay.com I think has a little to do with this. I just saw a 67 350 convertable go for over $25,000! That was for an unrestored car! I also seen two camaros sell in town here. One a 67 210hp 327 with 10 bolt, bolero red, a nice daily driver that leaked all kinds of fluids with a decent interior, needed paint, very near original, sold $9,999. A 68 with a 327, a very badly faked SS (even had a blacked out tail panel) bunch seat with a column shifted power slide, halfway decent paint went for $11,500. Both these cars were just barely 3's. I call them 20/20's, 20 feet and 20 miles an hour they looked good.
Protect the originality, change the drivetrain out if you have to have something that will blow the doors off of anything at a redlight. Paint it any way you want but don't try to pass it off for something it isn't. You will get much more respect this way.
