Is there a "rule" to how the vin #'s were stamped on the 68 Muncie for the Z28?  JM's book shows one that has a 1 before the vin, I guess to denote Chevrolet?  Like 18nxxxxx and Pontiac 28nxxxxx.  I talked to a guy rebuilding my trans and he said he hardly ever sees the 1 before the vin #.  Is this 1 just on Norwood, Los, 68 Z's, certain production runs or what?  Or is it just supposed to be there and sometimes it doesn't get put on?

It's always 18N392050 on the vin stampings in '68.  I have rebuilt more than I care to talk about.

It's stamped by the same machine that stamped your engine VIN.  Not only should the 1 be there, but the characters will always match the one on the engine pad.

That's what I was hoping, thanks again Jerry.  It would be 18Lxxx for LOS cars though right?

18Lxxxxxx for Los Angeles cars.  Also, the '68 Los Angeles built Camaros have the vin stamping on top of the transmission case.  This is where I found mine.

Is that fairly consistant?  I thought I had seen some on the side.

Yes, LA did that with any original 67-68 Muncie that I've seen.  Usually stamped at least three to four times.  On the very front part of the case, at the rear of the case, on the center bearing support, and the tailshaft lip.

Now that's something I didn't know and will have to check!  Is it always at least three to four times?

Never seen a transmission stamped more than once (except for maybe an overstrike).

I think I had a LA built 69 with it stamped probably four times on the top. Not overstrikes. Kurt probably has pics somewhere.

Were all Muncie's stamped with VIN's? Or just Z-28s

Pat

Other cars received Muncie's, with the associated VIN stamped on them, other than just the Z-28.

I think the stamping on LA Muncies depended on the mood of the plant worker.  Many LA Muncies have come in here for rebuild and resto and there is no consistancy to them at all.
