Non-SS '69 with 10 bolt and multileaf

[Steiner]

First off, I thought this should go in the research forum but there is not button for starting a new topic.  This is simply a notification of the following request on the chassis page:

"Note: GM documentation indicates that 1969 SS350s and LM1s with automatic transmissions received a 10-bolt rear axle. So far only SS350 cars with Powerglides have been observed to consistently have 10 bolt axles. Please contact us if you have a 1969 car with this drivetrain."


I have a 1969 model with not much documentation other than the trim tag.  It's a Norwood car with X44 code.  I do not believe it was an SS.

The engine block and transmission are not original ('78 block and '68 M20 with hacked hole for shifter by p.o.) however I believe the cylinder heads, rear end, and rear suspension are original.
Cylinder heads:  3932441 (indicate I believe either 250 or 255 hp motor)
Rear end :  L188 date code, PB0102G1 axle tube code, 10 bolt
5 leaf multileaf suspension

Sorry if this is the wrong place.  The webpage requested that this be posted in the forum.

Welcome to the site!

Yup, with an X44 tag, it originally was a 307 or a L65 350/250hp.
The multi-leaf spring axle, with the heads, confirms that it was a L65 originally.

The request on that page could have been worded better (and now is). We were looking for SS350 or LM1 cars with 10 bolts. No worries.

   I also have an 1243  x44 car with 10 bolt and multi leafs does that mean it was a 350?  I do not have the motor

[KurtS]

Yes, it was probably a L65 car then.
There's one minor exception - I kinda think that a 307 car with F41 spring option would have gotten multileafs. Never seen one to confirm and not many ordered....

Is there any way of knowing it was a 350 or 307 without the build sheet?

[KurtS]

Nope. But I'd assume L65.
