Since this topic has come up often, it would make sense to start a thread to outline some of these differences.

Raj, You mention:

"Bleed screw under vanity cover,
Different intake manifold (vanity cover mounting points are different)"

My January 1992 968 had the normal bleed screw and the updated intake. Only the very early cars have these. Another "very early" difference was the larger, edged rear 968 emblem.

Also Raj, didn't you spot something on my car with a bracket for pulling the engine?

Jeff

RajDatta

Good points guys.
Jeff you are correct, the engine hook to remove the engine on the earlier cars is on the alternator bracket, instead on the top bolt hole of the upper balance shaft housing.
Wonder if I should break it down in to very early cars and later 1992 cars.

HA! That would be good Raj! But how many of the early 92's were there?

RajDatta

Rob, Jeff has a very early 1992 and it has all the goodies you can imagine.
Raj

Most of these "unique" features were gone by November of 1991. so that would mean about 300 cabs and 150 coupes.

Wasn't there a difference in the exhaust tip between the early and later cars?

Also the change to 993 seats?

RajDatta

LTC, excellent catch!
Rolled exhaust Tip. I love them .

I have some pics of the changes from Jeff's car at Hershey, but rennlist is acting up and won't let me post pics...I'll try again later...

Here we go: Pic 1 is of the early bleed screw (or lack of), Pic 2 is the lift ring in a different spot, Pic 3 is lift ring in the rear, Pic 4 is of the strut mounts without the weights, and Pic 5 is how the AC is different.

Great shots steve. Don't use my A/C photo. It was converted to 134A so I don't know which parts are original and which aren't.

RajDatta

Thanks Steve for sharing the pictures. We never got to doing this post after Hershey like we had planned on.
Jeff, the later evaporators don't have blk paint. Also the harness connector is different.

More trivia....in my model year 1994 supplement book there is an explanation of some of the changes. One I have not see mentioned here is that the M490 HiFi stereo option changed--the speakers are different from the early year cars (says the guy who knows cuz he bought the wrong ones once...)
I'll dig the book up and list the others later.

RajDatta

M490 was the 10 speaker option which was offered through the years. I am not 100% positive if it was offered only on later cars. Jeff might know that better.
Raj

JonT

What I meant was M490 was offered all years but the part number for the speakers changed in mid 94.
I have the part numbers for the coupe M490 rear speakers early vs late cars somewhere.

PS a concours judge marked me down this year for my late 94 coupe not having the underhood glove box thingie. I was explaining something to a different judge at the back of the car at the time so I missed the chance to correct him.
