Where can one get points for a dual point distributor (1962 327 340 hp)? The major corvette supply houses don't seem to carry these. Is this something I can substitute from the local parts store?

You need 2 each of GM #12338659 aka Delco #D106P. These are available from any GM or Delco dealer. Equivalents are available as manufactured/distributed by Standard Motor Products under their part number DR 2270P.In Appreciation of John Hinckley -
Re: 62 dual point distributor
Danny, Go to NAPA and get CS786 or CS 786P. We use the 2nd one. Echlin supposedly bought out by Std but it's a confusing issue. The Echling points will easily go up to 7 grand on your dual point carb dist. FI also dual points. Get their condenser also. Stay away from the foreign made DR points. Even NOS points not the greatest. If you do use NOS clean off the "growth" on the contact. Stay away from NOS condensers with fiber board unless it's your own car as they come back to haunt you. I guess standard OK also. Accel has a cheep black cap and nice heavy duty rotor available if you can put up with looking at the gross lettering on top of it. NOS dual window caps big bucks. NAPA has or had a heavy duty black rotor but don't know if its still available. DO NOT use the cheep rotor as they tend to fly apart at high RPM and trash everything. These Echlin points can be used for '58 to 65 FI etc. If you can't get the correct matching condenser email me and I'll find the #. Watch the length of the ;ead wire. Echlins lead wire a mile long so if you buy it you will have to shorten it. Jumper wires for the points available at low cost from various sources. John D.Comment

Re: 62 dual point distributor
Standard Motor Products bought Dana's Controls Division a couple of years ago and Dana Controls owned the Echlin, BWD, and Echlin brand names, so whatever you buy today is essentially made by SMP. AC-Delco purchases parts from outside suppliers, but I'm not sure of their source for points.
If you google on any of these brand names you can find their sites and use the online application guide (make, year, model, engine, etc.) to find proper ignition parts for your engine, but be aware that not all are complete or accurate. They also all have decent online cross reference catalogs.
The '62 "dual window" dual point distributor is a unique system that uses the same contact set (2) as the single point distributor; '56-'61 dual point distributors use the same contact set (2) as the inline six-cylinder engine.
For single point or '62 dual point engines with redlines over 5500, I recommend the 28-32 oz. set, which is equivalent to the discontinued Delco D112P. The NAPA/Echlin equivalent is CS89, and you can cross reference this set on the other brands online cross reference catalogs.

Yes, the D112P or equivalent might be a better choice for higher RPM use. However, the D106P were what was originally installed in these distributors as they were supplied from the factory.
Also, I believe that most, if not all, of the point sets available today, with the possible exception of Accel, originate from the same manufacturing source and that source is located in Mexico.
By now, the market for these point sets has to be quite small. It's hard to imagine that manufacturing has not been "consolidated".In Appreciation of John HinckleyComment

Re: 62 dual point distributor
Danny, Don't want to argue with the senior citizens on the DB (I'm one also) But I suggest you don't use the heavy duty points Duke suggested. They will wear out your rare distribuor cam. Just go to NAPA and buy CS786P . We used them exclusively in all 58 to 65 FI distributors with 100% positive results. Thanks, JOhnComment

Re: 62 dual point distributor
John------
Distributor cam wear is the "downside" to using the heavier spring tension point sets. In fact, it's the only "downside" that I know of other than somewhat reduced contact set life due to rubbing block wear. I believe that the stock points were probably considered the best "compromise" between performance and parts wear. For most applications, they'll work just fine. For higher RPM operation, the higher tension sets might be the way to go.
Once-upon-a-time, distributor cam wear was not really a big deal----replacement cams were readily available. No more, though. They're one of the more difficult to find of distributor components. Most used examples are going to show wear and no new replacements that I know of are being manufactured at the present time. However, for the amount of miles that most vintage Corvettes see these days, I expect that regardless of the point set used, stock or high tension, the distributor cam is going to last a lot longer than the current owners will.
There is a way around this all. Convert to Breakerless electronic ignition. Then, wear on the distributor cam becomes pretty much irrelevent, even if it's severe wear. There are, of course, other benefits, too.In Appreciation of John HinckleyComment

Addendum
Also, the next time you purchase a set of those CS786P points, check the box carefully to see if it says "Made in USA", "Made Somewhere Else", or no reference, at all, to where they're made.In Appreciation of John HinckleyComment

Re: Addendum
Joe, WE stocked up on the points when we heard about the big transfer of powers. But I will order some just to check for you where they are now made. Hopefully they are not made too far from where you live. But everything else is so maybe they are OK!!! Can't define OK though. Thanks, JohnComment

Re: Addendum
John-----
Don't bother to order them just because of my interest if you already have a good supply; I could just as easily get a current set, myself. However, what do the "old stock" ones that you currently have say on the boxes? Does it say "Made in USA"?In Appreciation of John HinckleyComment

Re: Addendum
Joe, Box says Made in USA Napa Echlin. Other end of box says supplied for NAPA Distribution centers by DANA CORP. CS786P . Contacts line up perfect unlike some of the foreign ones. Has the slotted screw to hold the wire on. Nice high quality item. THese points were purchased earlier this year.
Also bought some old stock from ebay that are CS786. No P. Bougt a large quantity cheep. Will save them for some day when these good ones are history. After all how long can they continue to make quality ignition parts with such a low demand. Most of the NAPA distributor caps and rotors I see now have a small decal on them that says made in Mexico. The rotor still looks high quality though. The black caps I have seen are reboxed standards. JohnComment
