Ah-ha, so it is a baked enamel and I guess the Argent on the rally rims is the same?
I'm cleaning up some rims and finding the paint very tough to shift chemically, paint stripper doesn't do anything!

Was the Argent a satin/semi-gloss finish?

The photo's and info in this thread are pure gold!! Thanks JohnZ and everyone else for contributing  Smiley
3  Camaro Research Group Discussion / Restoration / Re: Help me with correct resto colors on a Qjet 7029202 on: February 08, 2014, 09:49:54 AM

Many of the small wire links (choke rod, pump arm rod, etc.) were originally clear, not yellow chromate. The idle adjuster screw is usually clear as are most of the external misc. springs. Same for the idle mixture screws & springs.


Of the q-jets I have, all 4 connecting rods [choke, pull-off, pump, sec. throttle] are yellow chromated, as is the ilde speed adjustment screw, but not it's spring.
The idle mixture screws and springs are not chromated either.

Yep, that's pretty much exactly how I've always seen them as well.
Yes, your right about the air valve and choke screws - with what appears to be star washers under the heads??
The choke flap and fast idle shaft & housing were also Teflon coated. The sec. air valve shaft appears to be the only one left silver.

Hi Kurt, thanks for chiming in here. Do you recall if Rochester applied the green ptfe coating to the shafts in-house [very high cure temps required]

Hi Jeff, this is a very old thread but I have a q or 2 regarding the pics of your carb.
All my forensic analysis of the cover over the hot idle compensator on a number of Rochester's, tells me that they were only zinc/cad plated, not yellow chromated?
Same goes for the secondary air valves and choke flap, I've never been able to find any evidence of yellow chromate on them either.

I think for certain that Jerry has one item not right on that carb, the screws that secure the air valves and throttle plate should be black?

I can only imagine that they wanted the aerial for am/fm to be front fender mounted, in order to keep the aerial lead as short as possible for least signal loss at fm frequencies.
8  Camaro Research Group Discussion / Originality / Re: BR or B-R on ignition coil can? on: November 04, 2013, 07:22:13 AM
I've chased this same question as well. As best as I can tell, early 68 models were br and then changed to b-r at some time during 68 calendar and certainly by the time 69's were rolling off the assembly line.
Would be good to try and narrow this one down.

b-r's are easy to find, br's are a pig! I only recently snared one off fleabay after years of hunting!!

... and have to say that the pointer drive is anything but quiet stepper motor precision, sounds more like a sewing machine!


Jeeziminy!

Is that normal for these radios? Did you contact the seller?

I've been considering one of these for a long time, but the uber high pricing has kept me at bay. Seems that for that price, it would support bluetooth streaming or have a usb port hidden somewhere in the back or via a extender wire.



Sorry for my long absence here. Yes, I contacted the seller and he was happy to give a full refund.
The concept is good and the finish is great, but the implementation both mechanically and electrically needs more refiinement.
10  Camaro Research Group Discussion / General Discussion / Re: beware of the look alike 68-Z28 fan on: January 09, 2013, 05:54:34 AM
The evidence that it is a welded and re-drilled fan is that the bolt holes are not in the correct radial position.
What appears to be the remanents original 3" holes on the painted side are in the correct radial position.

So, it is a rare fan in that it is a 4 rivet, though the ad could mislead if not carefully read.
The seller does not claim it to be an original 3.25" 4 rivet fan.
The seller does not claim it to be an extremely rare fan, only extremely rare fan blades [4 rivet]
The seller does mention that it has been machined, though does not specifically mention that this is because it has been welded and re-drilled.

So, probably still worth a good dollar being a 4 rivet, but would have been better to not have welded and redrilled it and to simply mention this as a possible mod in the ad.
There's probably a number of 3" 4 rivet hunters who are currently howling at what has been done here!

Just picked up one of these repro radios http://www.radiosforoldcars.com/newradio0F.htm and have to say that the pointer drive is anything but quiet stepper motor precision, sounds more like a sewing machine!
Have made a youtube vid of it http://www.youtube.com/watch?v=Da6oYGFUyzs

When slowly rotating the tuner knob for manual tuning, the pointer moves up and down as well as in and out, in a circular motion as it traverses the dial i.e. it corkscrews it's way along the dial, which strongly suggests to me that the stepper lead screw is running out of center, causing the sewing machine noise.
Let me know what you think.

Hi Steve, good to see you here!  Smiley
Yes, I can also vouch for the Plastex stuff - brilliant, especially the moulding bar!! Used it to re-create a bunch of mounting tabs on a VL Calais.

Hi Mark, sorry for my sloooww response [nearly 12 months!!  Shocked]
Not sure what my nephew came up with in the end, I think he found one locally [Australia] of the right ratio and reverse width [saginaw]
It's for a 1st gen GM-H Monaro [Aussie 'Camaro'  Smiley]
I've been reading up on soda blasting and it seems a safe way to go if you want to blast trans parts.
14  Camaro Research Group Discussion / General Discussion / GM differentials, C clips and clutch v. cone lsd's on: December 16, 2011, 10:26:17 AM
Hi all,
When did GM drop the usage of 'C' clips in Camaro's? I've read in another forum that they were still in use in '72 Chevelles.
Apparently, most Buick, Olds and Pontiac diffs were not C clip design.
Any breakdown of the usage of C clips across GM differentials and GM vehicles appreciated.

Also, any info on the usage of clutch [Eaton design?] versus cone lsd across the range also appreciated.
15  Camaro Research Group Discussion / Originality / BR v. B-R ignition coil changeover date on: December 13, 2011, 08:09:08 AM
Hi all, after much sifting through various forums including this one, it's not exactly clear as to when the change from BR to B-R embossing of the coil occurred.
What's the best timline estimate to date for this change?
Unfortunately, mine has somehow ended up with a 429 B-R fitted to it, when it should most certainly be a 293 and probably BR, not B-R

The best estimate I have so far from all I've read on this change, is sometime during the 68 model.
In another thread on this forum, Marty has said that he has seen 68's with BR and 69's with B-R, though another forum has quoted 68's with B-R
All help appreciated.
TIA
