? 69 Pace Car on EBay?

[jl8dale]

Here is a comparison of the Ebay Pace car rear axle stamp and mine on my LA Pacer.

They look pretty identical. My pic is the second one.

My car is a 04B and his is a 04C build date but they are very close in unit production numbers.

I thought all 69 SS including Z11's had 12 bolt posi?

[jl8dale]

12 Bolts but they don't have to be posi's.
I have (1) Pace Car now with the build sheet (BL rear) and just sold one a few months ago with a Protecto Plate and a (BL rear.)

Nope. True in 67 and 68, but in 69, SS350 cars with powerglides had 10 bolts. Pretty uncommon beast, but they exist.

Okay so now I'm more confused. I was asking if there were 12 bolt rears on 69 z-11's that are not posi units? Or were all 12 rears positraction ?

[KurtS]

Sorry.
So there's two parts - did all SS's have 12 bolts - no.
Did all SS's (or Z11's) have posi's - no. Posi was only required for 4.10 or deeper gears.

William pointed out that in 69, posi was required for 3.73 or 4.10 (Z was allowed a 3.73 open). I dug and it was only 67-68 that required posi with 4.10.

My car is L529677 also a LOS 04C build, Very close to the one for sale. <529407>

For comp,,,,, My tag = M044 His = J480

The Chassis Broadcast Copy (Mine) does in fact Have Z11,,,,,,"5Z11AA", "5Z87KM", "5Z720BA" typed in below all the data blocks.

Thanx for sharing this info.

Okay so I guess I do really need to get underneath and try to read the stamping on the axle to know for sure if I have a posi or not. Thanks Kurt for the information.

Kurt, 

I have a Z11 with powerglide and 10-bolt (PG) rear axle.  I believe you have some documented SS with powerglide, but as far as Z11, have you had any documented powerglide cars besides mine?

Steve,
Only one other Z11 car with a powerglide. And one Z10 car.

Do you have the VIN of that pace car?  I am wondering how close it is to mine.  I found another pace car that was owned by a guy I met at a show in Orlando, and he had a column shift pace car, that had a TH350 in it, but he said it had a PG when he got it.  His vin was near mine.  If this is a pattern, I wonder if maybe GM ran out of 12 bolts for a couple of days during this time frame.  Just a thought.
