So from Jerry's observations, it would seem that we at least have all 67's, 68's and early 69's using the wire clamp, then changing to the stamped steel clamp, with the changeover possibly somewhere early 69.
In any event, the wire clamp on my 12c built 68 would seem right. [whew!] Smiley

Perhaps other early 69'ers could chime in with what's on their motor to see if we can narrow down the changeover date.

Hi John, was that style of one piece clamp only a Z thing, with others receiving the two piece wire and saddle?

Is this the thread?

There were some variations

also my124677n, the bolt goes in from back to front. looks like you have a bolt through the front.
Well spotted!! Must have a nut on the other end of the bolt  Huh

Doesn't look too bad, though there may be something wrong at the bottom bracket as well, as the whole alternator 'seems' to be skewed such that the pulley end is pointing inboard.
Perhaps the bottom bolt is undersize [diameter] or some bushes are missing.
It's mostly the bottom bracket that sets the alignment, so everything has to be a close fit there.
Beware of flex fans. I seem to recall a story of one ejecting a blade through a hood.

Nice ride btw!!  Smiley

The water pump looks fine with short legs and close to the timing cover.
Water pump pulley to crank pulley alignment looks right too [hard to tell in the pic though] so I'd guess it's only an alternator position problem.
'Banging' the bracket forward sounds a bit harsh!  especially by the amount you quote Shocked
Post up a pic of the alternator and bracket.

btw, that's a head twisting pic - trying to separate the timing cover from the pump backing plate!!

Going by Seymours web, it should be the same color, but lower temp rating [250f v 300f] and even higher gloss.
EN-48 would still be preferable on these two counts.

Durability is also less - good v excellent.

Fin combs like this one are cheap and readily available from most a/c parts suppliers.

Ah that's right, that's the format I remember. It must have been another site that had those syntax's included in the hover pop-up description.
Cheers.
41  Camaro Research Group Discussion / Originality / Re: 68 396 L34 Q-jet vacuum to AIR valve on: December 17, 2010, 09:17:13 AM
Yes, L30 A3 of the AIM clearly shows the smog valve vacuum connecting to that carby port.
L35 A7 shows the same thing, though not quite so clearly.
Veiw 'A' of KD1 A1 is not clear at all, almost looks like a 'T' fitting that's being capped off  Undecided

btw Ed, how did you construct that href link to the emissions pdf ?
Hovering on the Insert Hyperlink icon doesn't reveal the syntax anymore, or am I thinking of another site ??
42  Camaro Research Group Discussion / Originality / Re: 68 396 radiator cap on: December 16, 2010, 05:55:50 AM
Yes, I meant zinc plated, not galvanized.
John, yours looks to be more heavily stamped, giving and almost embossed look to the text and the circle around the AC and RC-15 being slightly depressed below the surface of the surrounding metal, which is exactly how I remember them from those days.

While we're on the subject, below is a couple of before and after cleaning pics of my '86 VL Commodore cap [GMH built car].
They weren't using AC caps by then, they were all built by another local company - CPC.
 
I cleaned it with CLR bathroom tile cleaner which is a weak organic acid [I think], spraying a bit on, then gentle scrubbing with a soft toothbrush then rinse off.
It only took about 20 secs for each side. I moved as quickly as I could so the acid had little to no chance of attacking the zinc.

I then phoned CPC to see if they could rebuild it for me, as all the rubber bits were shot.
To my shock and surprise, instead of the expected loud laughing ["You want us to do what!!... Cheesy] I was put through to a guy who said "Sure, no probs, send it over and I'll do it for you"
After I got up off the floor, I asked him how much. He said he'd do it for free!!   Shocked

The last couple of pics are how it looked after coming back from CPC.

Can't say that this is one I have is 'correct', but should be somewhere near the mark.
It's been re-plated and may be much brighter than original. Here in Au, AC caps fitted to GMH cars from the same era were steel with more of a gray galvanized finish.
Not sure that any caps from any manufacturer were stainless in those days.

John, was there one cap that was more common than the others?

Cheers Mark  Smiley
I see it's a L34 with ps and a/c and it appears that it's still a single groove water pump pulley? The a/c and ps belts are direct to crank?
45  Camaro Research Group Discussion / Originality / Re: Single groove L34 water pump pulley on: December 12, 2010, 11:43:54 AM
My apologies Boston14, what you said previously is perfectly clear. I've been staring at this screen too long and are loosing the plot!!
Read Martys post upside down - early is smooth and later is ribbed.

Does anyone have a engine bay pic of a 69 bb with ps, a/c and smog?
Is that the smog pump under the alternator in Paceme's 69 pic above?

If that's so, then the single groove for bb would have found usage on 67's [different emissions standard] and 69's [different component arrangement], but as best as I can tell, not 68's, not even exports with AIR delete [if mine is anything to go by]
